Page 2: Purpose Of This Manual
Description The Greenlee CM-660, CM-860, CM-960, CMH-600, and CMI-600 Clamp Meters are hand-held testing devices with the following measurement capabilities: AC and DC voltage, AC current, AC current AmpTip™, frequency, non-contact electric field (EF) detection, and resistance. They also check diodes and verify continuity. These meters are designed to be placed on or removed from insulated or uninsulated conductors. -

Using the Features All Models • REC: Press momentarily to activate MAX/MIN/AVG recording mode. and “MAX MIN AVG” appear on the display. The meter beeps when new maximum or minimum reading is updated. The average reading is calculated over time. Press the button momentarily to read the MAX, MIN and AVG readings in sequence. - Page 9 CM-660 • CM-860 • CM-960 • CMH-600 • CMI-600 Using the Test Leads Electric shock hazard: The test leads supplied with this product comply with safety standards that limit the exposed length of the probe tip to 4 mm for measurement categories III and IV. These test leads include a cap that must be in place when used in measurement category III or IV applications.
- Page 10 AC Measurement AC measurements are usually displayed as RMS (root mean square) values. The RMS value is equal to the value of a DC waveform, which would deliver the same power if it replaced the time-varying waveform. Two AC measurement methods are average-re- sponding RMS calibrated and true RMS-reading.

Page 11: Operation
CM-660 • CM-860 • CM-960 • CMH-600 • CMI-600 AC Bandwidth AC bandwidth is the range of frequencies over which AC measurements can be made within the specified accuracy. It is the frequency response of the AC functions—not of the frequency measurement functions. A meter cannot accurately measure the AC value with frequency spectrums outside its bandwidth. -
