Frequently Asked Questions - CMP-3000 Sonel

How do I measure AC current with the clamp?

Set the rotary switch to 1000A or 3000A (for flexible probe). For 1000A, press MODE to select AC (~). Use the trigger to open the clamp and encircle only one conductor. Read the display. For 3000A, connect the flexible clamp to COM and VΩ terminals, then clamp around the conductor.

How do I use the non-contact voltage detector?

Set the rotary switch to any position. Touch the tip of the detector (top of the meter) to the object. The indicator light glows red when AC voltage is present (10..1000V AC). Test on known live source first.

How do I enable Bluetooth on the CMP-3000?

Press and hold the button (bottom right) for 2 seconds. The Bluetooth icon appears on the display. The meter is visible as 'CMP-3000' in the Bluetooth manager of your Android device. Use the Sonel Multimeter Mobile app.

What does 'OL' on the display mean?

OL indicates Overload: the measured value exceeds the selected range. Switch to a higher range manually or enable auto-ranging. If OL appears in all ranges, the input may be too high for the meter's protection.

How do I replace the battery?

Turn the rotary switch to OFF. Remove test leads. Unscrew the single screw on the back cover. Lift the cover, remove the old 9V battery (6LR61), insert a new one observing polarity, replace cover, and tighten screw. Do not use the meter with the cover removed.

How do I measure inrush current (INRUSH)?

Set to AC current (1000A or 3000A). Briefly press the INRUSH/PEAK button. Clamp around the power cord of the device. Turn on the device; the meter captures the starting current within 106 ms. Read the result.

What is the accuracy for DC voltage measurement?

For ranges up to 500.00V: ±(0.1% of reading + 4 digits). For 1000.0V range: ±(0.2% of reading + 5 digits). Input impedance 10 MΩ, overload protection 1000V DC/AC RMS.

How do I use the REL function for relative measurements?

While in a measurement mode (except diode test), briefly press the REL/Hz button. The current reading is stored as reference, and the display shows zero. Subsequent readings are the difference from that reference. Press REL again to exit.

What is the maximum input voltage for resistance or capacitance measurements?

Do not apply more than 250V DC/AC RMS to the terminals when measuring resistance, capacitance, diode, continuity, frequency, or duty cycle. Exceeding this may damage the meter.

How do I clean and maintain the CMP-3000?

Keep the meter dry. Wipe the housing with a damp cloth; do not use chemicals, solvents, or detergents. Remove batteries if storing for more than 60 days. Store in normal temperatures (-20..+60°C) and low humidity (<80%).

2 Safety

2.1 General rules

In order to provide conditions for correct operation and the correctness of the obtained results, the following recommendations must be observed:

• before using the meter read carefully this manual,
• the meter should be operated only by qualified persons that have passed health and safety training,
• be very careful when measuring voltages exceeding (as per IEC 61010-1:2010/AMD1:2016):

Normal locations	Wet locations
60 V DC	35 V DC
30 V AC RMS	16 V RMS
42.4 V AC of peak value	22.6 V AC of peak value

as they generate a potential risk of electric shock,

• do not exceed the maximum limits of the input signal,
• during the voltage measurements do not switch the device in the current or resistance measuring mode and vice versa,
• when changing ranges, always disconnect the test leads from the tested circuit,
• hold the measuring probes by the spot provided, restricted by a special barrier to avoid accidental contact with exposed metal parts,
• If during the measurement symbol OL appears on the screen, it indicates that the measured value exceeds the measurement range,

- It is unacceptable to operate:

⇒ a damaged meter which is completely or partially out of order,
⇒ a device with damaged insulation of test leads,
⇒ a meter stored for an excessive period of time in disadvantageous conditions (e.g. excessive humidity).

- repairs may be carried out only by an authorised service point.

WARNING

• Never start the measurements if you have wet or damp hands.
• Do not perform measurements in explosive atmosphere (e.g. in the presence of flammable gases, vapours, dusts, etc.). Using the meter in such conditions may result in sparking and cause an explosion.

The limit values of the input signal
Function	The maximum input value
3000 A AC	3000 A AC
1000 A AC/DC	1000 A AC/DC
V DC, V AC	1000 V DC/AC RMS
Resistance, continuity, diode test, capacitance, frequency, duty cycle	250 V DC/AC RMS
Temperature	30 V DC, 24 V AC

2.2 Safety symbols

This symbol located near another symbol or terminal, indicates that the user should read the further information contained in the manual.

This symbol located near the terminal, indicates that in normal use there is a possibility of dangerous voltages.

Protection class II – double insulation

Terminals with this marking cannot be connected to a circuit where the voltage to ground exceeds the maximum safe voltage of the device.

3 Preparing the meter for operation

After purchasing the meter, check whether the content of the package is complete.

Before performing the measurement:

• make sure that the battery level is sufficient for measurements,
• check whether the meter casing and insulation of the test leads are not damaged,
• to ensure consistent measurement results it is recommended to connect black lead to COM terminal and red lead to other terminals,
• when the meter is not in use, set the function switch in OFF position.

The device has the AUTO-OFF function triggered after approx. 30 minutes of user inactivity. To turn the meter on again, set the function switch to OFF position and then set it at the desired function.

WARNING

• Connecting wrong or damaged leads may cause electric shock.
• The meter must not be connected to the voltage source when it is set to current or resistance measurement or to diode test. Failure to observe this precaution may damage the meter!

When using the meter, be sure to:

• discharge capacitors in the tested power sources,
- disconnect the power supply when measuring the resistance and diode tests,
- turn off the meter and disconnect test leads before removing the back cover to replace the battery.

WARNING

Do not use the meter if the cover of battery compartment is removed.

It is possible that in certain low ranges of AC or DC voltage, when the meter is not connected to the leads, the screen will show random and variable readings. This is a normal phenomenon, which results from the input sensitivity with high input resistance. When connected to a circuit, the read-out will stabilize and the meter will provide the correct value.

5 Measurements

The content of this chapter should be thoroughly read and understood since it describes methods of measurements and basic principles of interpreting measurement results.

5.1 Current measurement

WARNING:

Disconnect the test leads before measuring current using clamp.

5.1.1 Range of 3000 A

To perform the current measurement:

• set the rotary switch at 3000A,
• connect flexible clamp to COM and VΩ →●Hz%CAPTemp sockets,
• fasten the clamp around the tested conduit. Only one conduit must be within the testing range of the clamp,
• read the measurement result on the display.

5.1.2 Range of 1000 A

To perform the current measurement:

• set the rotary switch at 1000A,
• press MODE button to display the following symbol:
  ⇒ , if you are measuring alternating current,
  ⇒ , if you are measuring direct current,

- use the clamp-opening trigger and attach the clamps on the tested conduit. Only one conduit must be within the testing range of the clamps,

- read the measurement result on the display.

If DC current is measured and the meter is not attached to the tested circuit, but it still indicates a non-zero value, then you must reset it by briefly pressing REL/Hz button.

5.2 Non-contact voltage detector

WARNING

• The detector is designed to detect the presence of a voltage, not for determining its absence.
• Electric shock hazard. Before using the tester, check if its operational by testing it on a known AC voltage (i.e. next applicable socket with live voltages).

To activate the detector:

• set the rotary switch at any position,
• touch the tip of the detector to the tested object.
  If the AC voltage is present, the indicator light will glow red.

• The wires in the extension cords are often twisted. For best results, move the tip of the detector along the wire to locate the live line.
• The indicator has a high sensitivity. It can be randomly actuated by static electricity or other energy sources. This is normal.
• The type and thickness of the insulation, distance from the power source, shielded cables and other factors may affect the operation of the tester. If you are unsure about the test result, check the presence of voltage in a different way.

5.3 Voltage measurement

WARNING

• Electric shock hazard. The ends of measuring probes, due to their length, may not reach the live parts inside some network connections of low-voltage electrical equipment, because the contacts are arranged inside the sockets. In such a case, the read-out will be 0 V with the simultaneous presence of voltage in the socket.
• Before acknowledging the absence of voltage in the socket make sure that the ends of the probe touch the metal contacts inside the socket.

CAUTION!

Do not measure the voltage when an electric motor located within the circuit is being switched on or off. Resulting voltage spikes may damage the meter.

To perform AC voltage measurement:

• set the rotary switch at V ≈ Hz or ≈ mV,
• press MODE button to display the following symbol:
  ⇒ , if an alternating voltage is to be measured,
  ⇒ , if a constant voltage is to be measured,
• connect black test lead to COM terminal, and red test lead to VΩ →Hz%CAPTemp terminal,
• contact the tips of test probes to the points of measurement,
• read the measurement result on the display.
