Using the Features

All Models

• Intelligent Auto Power Off (APO): The meter automatically turns off after approximately 32 minutes of inactivity to extend battery life. Active meter function is specified as: selector switch is rotated or pushbuttons are pressed; readings above 8.5% of the range; non-OL readings for resistance, continuity, or diode function; non-zero readings for Hz function; phase rotation segment moving. To wake up the meter from APO, press the SELECT button momentarily and release or turn the rotary switch OFF and then back on. Always turn the rotary switch to the OFF position when the meter is not in use.

• : Press the button momentarily to toggle the LCD backlight. The backlight automatically turns off after 32 seconds to extend battery life.

• : Press the button momentarily to toggle the flashlight. The flashlight automatically turns off after 32 seconds to extend battery life.

• C CREST: Press for 1 second to activate. LCD will C indicate when mode is active. This mode will capture current or voltage peaks in duration of as small as 5 ms. Press CREST to toggle between MIN and MAX. Add 250 digits to accuracy for changes > 5 ms.

• H HOLD: Press momentarily to hold the present value on the display. Press again to exit this mode.

• R REC: Press momentarily to activate MAX/MIN/AVG recording mode. R 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. Press the button for 1 second to exit MAX/MIN/AVG recording mode. APO is disabled automatically in this mode.

• SELECT: Press momentarily to toggle between functions, measurement modes, or display modes. The last used setting becomes the default when that function is selected again. To change the default, select a new setting. The setting will be stored in nonvolatile memory.

• ∆: Press the ∆ button for 1 second to toggle between zero and normal mode. In zero mode the value on the LCD when the button is pressed becomes the offset. As the input value changes, the offset is subtracted from the actual value. This modified value is shown on the LCD.
  Note: ∆ operation when DCA or DC + ACA functions are selected offsets any magnetic hysteresis in the jaw. If DCA or DC + ACA reading before measuring is not zero, press the ∆ button for 1 second. The LCD will display “dc_0”. When this clears, the meter is ready for operation. When measuring more than 5 A, this mode is disabled. As an indication, the meter will beep three times. CM-1560, CMH-1000, and CMI-1000 Only

• PEAK-RMS: Press the PEAK-RMS button for 1 second to activate PEAK-RMS mode to capture inrush current or voltage in duration as short as 80 ms. P-RMS appears on the display. Press the button for 1 second to exit PEAK-RMS mode. APO is disabled automatically in this mode.

• and : If desired, press and hold the REC button while turning the meter ON to enable the Beeper feature. If the segments indicate a clockwise movement, the beeper sounds a single long beep per segment cycle. If the segments indicate a counterclockwise movement, the beeper sounds three short beeps per segment cycle.

• : Ensure the motor is electrically isolated from its power source. Press the SELECT button momentarily to select Motor function. Connect the meter to the motor as described in the “Settings Table” section of this manual. From the perspective of looking down the shaft of the motor, spin it clockwise. If the meter indicates a clockwise movement, the motor leads connected to L1, L2, and L3 of the meter are T1, T2, and T3, respectively. If the meter indicates a counterclockwise movement, swap any two connects between the meter and motor. Then retest.

• : Press the SELECT button momentarily to select Phase function. Connect the meter to the phases as described in the “Settings Table” section of this manual. If the meter indicates a clockwise movement, the phases connected to L1, L2, and L3 of the meter are L1, L2, and L3, respectively. If the meter indicates a counterclockwise movement, swap any two connects between the meter and phases. Then retest.

Using the Test Leads
WARNING
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.
Failure to observe this warning could result in severe injury or death. 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-responding RMS calibrated and true RMS- reading.
The average-responding RMS calibrated method takes the average value of the input signal after full wave rectification, multiplies it by 1.11, and displays the result. This method is accurate if the input signal is a pure sine wave.
The true RMS-reading method uses internal circuitry to read the true RMS value. This method is accurate, within the specified crest factor limitations, whether the input signal is a pure sine wave, square wave, triangle wave, half wave, or signal with harmonics. The ability to read true RMS provides much more measurement versatility. The Greenlee CM-1360, CM-1560, CMH-1000, and CMI-1000 are true RMS meters.
The Waveforms and Crest Factors table shows some typical AC signals and their RMS values.
Waveforms and Crest Factors

Waveform| | | |
---|---|---|---|---
RMS Value| 100| 100| 100| 100
Average Value| 90| 100| 87| 64
Crest Factor* | 1.414| 1| 1.73| 2

• The crest factor is the ratio of the peak value to the RMS value; it is represented by the Greek letter .
  AC + DC True RMS
  AC + DC true RMS calculates both of the AC and DC components given by the expression when making measurements and responds accurately to the total effective RMS value regardless of the waveform. Distorted waveforms with the presence of DC components and harmonics may cause:

  • Transformers, generators, and motors to overheat
  • Circuit breakers to trip prematurely
  • Fuses to blow
  • Neutrals to overheat due to the triplen harmonics present on the neutral
  • Bus bars and electrical panels to vibrate
    CM-1560 and CMI-1000 can be set to display AC true RMS or AC + DC true RMS.

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. Complex waveforms, noise, and distorted waveforms contain frequency components that are much higher than the fundamental; for example, high frequency noise on a 50/60 Hz power line.

Operation

WARNING
Electric shock hazard:
Contact with live circuits could result in severe injury or death.
