Introduction The CM65 is a 600 A True RMS Clamp Meter designed to meet the chal- lenges of the solar, alternative/renewable energies, and utilities industries. The supplied MC4 test leads help you troubleshoot photovoltaic systems and keep them running efficiently. The CM65 accurately measures voltage, current and other electrical parameters to ensure proper installation of PV systems.
Safety 3.1 General Safety Information This user manual contains information and warnings that must be followed for operating the instrument safely and maintaining the instrument in a safe oper- ating condition. If the instrument is used in a manner not specified by the man- ufacturer, the protection provided by the instrument may be impaired.
Safety WARNING The accompanied test probe assembly meets UL/IEC/EN61010-031 Ed. 1.1 to 10A maxi- mum at 140℉ (60℃). IEC 61010-031 requires exposed conductive test probe tips to be ≤ 4 mm for CAT III & CAT IV ratings. Refer to the category markings on your probe assem- blies as well as on the add-on accessories (detachable Caps or Alligator Clips, etc.), if any, for applicable rating changes.

Meter Operation CAUTION Before operating the device, you must read, understand, and follow all instructions, dan- gers, warnings, cautions, and notes. NOTE When the meter is not in use, the function switch should be set to the OFF position. CAUTION When connecting the probe leads to the device under test, connect the negative lead be- fore connecting the positive lead.
Meter Operation Figure 5.1 Auto Range Display Icon 5.4 Out-of-Range Alert If the input is out-of-range, OL is displayed. Please do not attempt to make measurements beyond the specified ranges of the meter. 5.5 Display Hold Function After taking a measurement, short press the HOLD button to freeze a reading. Press the HOLD button again to return to normal operation.
Meter Operation Figure 5.2 Basic Voltage Measurement Setup 1. Set the function switch to the Voltage position 2. Short press the MODE button to select AC or DC voltage mode. 3. Insert the black test lead into the negative (COM) terminal and the red test lead into the positive terminal.
Use caution when the measured voltage is greater than 30V DC or AC rms. The VFD feature in the CM65 eliminates high frequency noise in AC voltage measurements by means of a low pass filter. The VFD mode is designed for variable frequency drive measurements.
Meter Operation Figure 5.3 Millivolt Measurements 1. Set the function switch to the millivolt position 2. Short press the MODE button to select AC or DC voltage mode. 3. Insert the black test lead into the negative (COM) terminal and the red test lead into the positive terminal.

Meter Operation WARNING Do not use the meter to measure current above the rated frequency. This may cause the magnetic circuits in the jaws to reach hazardous temperatures. WARNING Disconnect the test leads from the meter before taking Clamp measurements. Clamp Measurement Considerations •...
Meter Operation 2. Short press the MODE button to select AC or DC current mode. 3. For DC current mode, with no conductor in the clamp, use the DC Zero menu icon to zero the display (see the Function Icons section for complete details).
Meter Operation 2. If necessary, short press the MODE button to select the Resistance func- tion k . 3. Insert the black test lead into the negative (COM) terminal and the red test lead into the positive terminal. 4. Place the probe ends of the test leads in parallel to the part under test. 5.
Meter Operation 3. Insert the black test lead into the negative (COM) terminal and the red test lead into the positive terminal. 4. Place the probe ends of the test leads in parallel to the part under test. 5. If the measurement is <30 Ω, the meter will beep. If the measurement is > 480Ω, the meter will not beep.
Meter Operation 4. Take two diode measurements, one in forward bias and one in reverse bias. This can be accomplished by, first, placing the probe ends of the test leads in parallel to the part under test in one direction and then taking a second measurement in the reverse polarity orientation.

Meter Operation Figure 5.8 Thermocouple Temperature Measurements 1. Set the function switch to the Temperature position . 2. Use the MODE button to select the Temperature mode. 3. Insert the banana plug Type-K temperature probe into the meter’s input terminals observing correct polarity. A plug adapter with banana plug to Type-K socket (to adapt to other Type-K standard mini plug temperature probes) can be obtained optionally.
Figure 5.9 External Clamp Adaptor Test Setup 1. Set the CM65 function switch to the external clamp adaptor position 2. Connect the external clamp adaptor to the CM65 by inserting the signal leads from the external clamp to the input terminals on the CM65, observ- ing correct polarity.
