Frequently Asked Questions - 3335 PeakTech

How to change the battery of the PeakTech 3335?

Turn off the device and disconnect all cables. Unscrew the 2 screws of the battery compartment on the back, remove the cover, replace the old battery with a new 9V battery, then close. Never use the device with the compartment open.

How to measure DC voltage with this multimeter?

Turn the selector to a V range (200 mV to 600 V). Connect the red lead to V/Ω/CAP/Hz/Temp and the black to COM. Place the probes on the circuit. If the value is unknown, start with the highest range. The display shows the voltage with automatic polarity.

What does "OL" on the screen mean?

"OL" indicates an overload of the selected measurement range (OverLoad). Select a higher range to obtain a correct reading. It can also mean an open circuit in resistance mode.

How to use the Data Hold function?

Press the HOLD button (7) until the "HOLD" symbol appears on the screen. The measured value is then frozen. Press again to release.

What are the essential safety precautions?

Never exceed 600 V DC/AC at the inputs. Do not use the device if it is open or damaged. Disconnect the leads before changing functions. Wear dry clothing and isolate yourself. Respect the overvoltage categories (CAT III 600 V max).

How to measure a current greater than 200 mA?

Use the 10 A input and the red lead on the 10 A jack, black on COM. Set the selector to 10 A (AC or DC). Connect in series in the circuit. Limit the measurement to 30 seconds maximum, then wait 15 minutes before the next measurement.

The display shows ghost values, what to do?

This is normal in sensitive low ranges. Short-circuit the test probes: the display should return to zero. If not, check the leads. This disappears as soon as you measure a signal.

How to clean the multimeter?

Use a damp, lint-free cloth with a mild detergent. Do not let any liquid enter the device. Do not use abrasive products. Wipe and let dry before use.

How to replace a fuse?

Turn off the device and remove all leads. Unscrew the 5 screws of the lower housing. Replace the defective fuse with an identical one: F1 (200 mA/600 V, 5x20 mm) or F2 (10 A/250 V, 6.3x32 mm). Close the housing. Only a qualified technician should proceed.

What is the overvoltage category and what does it mean?

The PeakTech 3335 is certified CAT III 600 V. This means it can measure on fixed power circuits (distribution boards, outlets) up to 600 V to ground, with protection against transients. Do not use it on CAT IV circuits without appropriate equipment.

5. Preparation for Operation

5.1. Using the test leads

CAUTION!

Note on using the supplied safety test leads according the IEC / EN 61010-031:2015:

Measurements in the field of overvoltage category CAT I or CAT II can be performed with test leads without sleeves with a maximum of up to 18mm long, touchable metallic probe, whereas for measurements in the field of overvoltage category CAT III or CAT IV test leads with put on sleeves, printed with CAT III and CAT IV must be used, and therefore the touchable and conductive part of the probes have only max. 4mm of length.

Use only the identical type of test leads supplied with your meter. These test leads are rated for 1200 V.

Cautions!

* Although the replacement probes are rated for 1200 V, the maximum rating of your meter is 600 V DC/AC. If you try to measure DC voltages above 600 V or AC voltages 600 V rms, you might damage your meter and expose yourself to a serious shock hazard. Use extreme care when you measure high voltages.

* Never connect the probe you plug into the COM terminal to a source of voltage greater than 600 V DC/AC _rms with respect to earth/ground. This creates a serious shock hazard.

5.2. Using the stand

Use your meter's stand to prop up the meter. If you prop your meter on a bench-top, the stand helps provide a better viewing angle.

To use the stand as a prop, just open it away from the meter and set it on a flat surface.

6. How to make measurements

6.1. Measuring AC/DC voltage

Understanding Phantom readings:

In some DC and AC voltage ranges, when the test leads are not connected to any circuit, the display might show a phantom reading. This is normal. The meter's high input sensitivity produces a wandering effect. When you connect the test leads to a circuit, accurate reading appears.

Warning!

Do not try to measure a voltage greater than 600 V DC/AC. You might damage your meter and expose yourself to a severe shock hazard.

Follow these steps to measure DC/AC Voltage.

1. Set the rotary selector to the desired position. Select the range as required for the voltage level to be measured. If you do not know the voltage level, start with the range switch set to the highest voltage position and reduce the setting as needed to get a reading.
2. Plug the black test lead into the meter's COM terminal and the red test lead into the V/Ω/CAP/Hz/Temp.- terminal.
3. Connect the test leads to the DC/AC voltage source you want to measure.

Warning! When you connect the test probes to an AC outlet, do not turn the rotary selector switch to another range. It could damage the meter's internal components or injure you.

6.2. Measuring AC/DC Current

Warning!

* Do not apply voltage directly across the terminals. You must connect the meter in series with the circuit.

* The 10 A terminal is fused. A severe fire hazard and short circuit danger exists if you apply a voltage with high-current capability to this terminal. The meter can be destroyed under such conditions.

To measure current, break the circuit and connect the probes to two circuit connection points. Never connect the probes across a voltage source in parallel. Doing so can blow the fuse or damage the circuit under test.

Note: The maximum input current is 0,2 A or 10 A depending on the terminal used. In these ranges excessive current blows the fuses, which you must replace.

1. Set the rotary selector to the desired A range. If you do not know the current level, set it to the highest position and reduce the setting as needed to get a reading.
2. Plug the black test lead into your meter's COM terminal and the red test lead into your meter's mA or 10 A terminal.
3. Remove power from the circuit under test and then break the circuit at the appropriate point.
4. Connect the test leads in series with the circuit.
5. Apply power and read the current. Your meter displays the current value.

Note: If you see the meter for DC current, “-” appears or disappears. This indicates the polarity of the measured current.

6.3. Measuring Resistance

Warning!

* Never connect the test leads to a source of voltage when you have the selected the OHMS function and plugged the test leads into the V/Ω/CAP/Hz/Temp.-terminal.

* Be sure that the circuit under test has all power removed and that any associated capacitors are fully discharged before you make a resistance measurement.

The resistance measuring circuit compares the voltage gained through a known resistance (internal) with the voltage developed across the unknown resistance. So, when you check in-circuit resistance, be sure the circuit under test has all power removed (all capacitors are fully discharged).

1. Set the rotary selector to the desired OHM range.
2. Plug the black test lead into your meter's COM terminal and the red test lead into your meter's V/Ω/COM/Hz/Temp.-terminal.
3. Connect the test leads to the device you want to measure.

Notes:

* If the measured resistance value exceeds the maximum value of the range selected, "OL" appears flashes. This indicates an overload. Select a higher range. In this mode the beeper does not sound.

* When you short the test leads in the 200 Ω range, your meter displays a small value (no more than 0.3 Ω). This value is due to your meter's and test leads internal resistance. Make a note of this value and subtract it from small resistance measurements for better accuracy.

6.4. Measuring Frequency

Warning!

If you try to measure the frequency of a signal that exceeds 250V AG_ms , you might damage your meter and expose yourself to a severe shock hazard.

Follow these steps to measure the frequency of a signal:

1. Set the rotary selector to FREQ.
2. Plug the black test lead into your meter's COM terminal and the red test lead into you meter's V/Ω/CAP/Hz/Temp.-terminal.
3. Connect the test leads to the frequency source.

Warning! When you connect the test leads to an AC outlet, do not turn the function rotary selector to another range. It could damage the meter's internal components or injure you.

Note: For the most accurate measurements, we strongly recommend you to use a BNC cable with ferrite core.

6.5. Capacitance measurements

Warning!

To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any capacitance measurements. Remove the batteries and unplug the line cords.

1. Set the function switch to the CAP position.
2. Plug the black test lead into your meter's COM terminal and the red test lead into your meter's V/Ω/CAP/Hz/Temp.- terminal.
3. Touch the test leads to the capacitor to be tested. The display will indicate the proper decimal point value.

6.6. Temperature measurements

Warning!

To avoid electric shock, disconnect both test probes from any source of voltage before making a temperature measurement.

1. If you wish to measure temperature in °F, set the function switch to the °F range. If you wish to measure temperature in °C, set the function switch to the °C range.
2. Insert the Temperature probe into the negative (-) jack (COM) and the positive (+) jack (Temperature), making sure to observe the correct polarity.
3. Touch the Temperature probe head to the part whose temperature you wish to measure. Keep the probe touching the part under test until the reading stabilizes (about 30 seconds).
4. Read the temperature in the display. The digital reading will indicate the proper decimal point and value.

6.7. Checking Continuity

Warning!

Never perform a continuity measurement on a circuit that has power connected.

Follow these steps to check a circuit's continuity.

1. Set the rotary selector to (((o)))
2. Plug the black test lead into your meter's COM terminal and the red test lead into your meter's V/Ω/CAP/Hz/Temp.- terminal.
3. Remove power from the circuit.
4. Connect the test leads to the circuit.

Note:

The buzzer sounds if the measured resistance is below about 50 Ω approximately.

6.8. Checking diodes

This function lets you check diodes and other semiconductors for opens and shorts. It also lets you determine the forward voltage for diodes. You can use this function when you need to match diodes.

1. Set the rotary selector to the diode position.
2. Plug the black test lead into your meter's COM terminal and the red test lead into your meter's V/Ω/COM/Hz/Temp.- terminal.
3. Connect the test leads to the diode you want to check and note the meter reading.

Notes:

* If the display shows a value for example 0.2 for a germanium diode or 0.5 for a silicon diode, reverse the diode. If the meter indicates and overrange, the diode is good. The displayed number is the diode's actual forward voltage (up to 2.0 volts).

* If the display indicates an overrange condition “OL”, reverse the polarity of the connection. If the display shows a value, the device is good. The displayed value is the component’s actual forward voltage (up to 2.0 volts). If the display still indicates an overrange condition, the device is open.

* If the display shows a value both before and after you reverse the polarity, the device is shorted.

When you connect the diode to the meter and the meter displays the devices forward voltage, the red test lead is connect to the diodes anode, and the black test lead is connected to the diode's cathode. This meter supplies enough forward voltage to light most LED's. However, if the LED's forward voltage is greater than 2.0 volts, the meter incorrectly indicates that the device is open.

7. Care and Maintenance

7.1. Installing the battery

Your meter requires a 9 V battery for power. The battery symbol appears when the battery voltage drops to the certain limits. For proper operation, replace the battery as soon as possible. Continued use with a low battery will lead to abnormal readings.
