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.38

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//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.39 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.40 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//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//COM/Hz/Temp.-terminal.

3. Connect the test leads to the device you want to measure.

• 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 range, your meter displays a small value (no more than 0.3 ). 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.41 6.4. Measuring Frequency Warning! If you try to measure the frequency of a signal that exceeds 250V AC rms

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//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//CAP/Hz/Temp.- terminal.

3. Touch the test leads to the capacitor to be tested. The display will

indicate the proper decimal point value.42 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//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 approximately.43 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//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.44
