SAFETY ALERT SYMBOL

Immediate hazards which, if not avoided, WILL result in severe injury or death.

Hazards which, if not avoided, COULD result in severe injury or death.

Hazards or unsafe practices which, if not avoided, MAY result in injury or property

damage.

Important Safety Information

Electric shock and fire hazard:

• Do not expose this unit to rain or moisture.

• Do not use the unit if it is wet or damaged.

• Use test leads or accessories that are appropriate for the application. Refer to the

category and voltage rating of the test lead or accessory.

• Inspect the test leads or accessory before use. They must be clean and dry, and the

insulation must be in good condition.

• Use this unit for the manufacturer’s intended purpose only, as described in this

manual. Any other use can impair the protection provided by the unit.

Failure to observe these warnings can result in severe injury or death.

Electric shock hazard:

• Do not apply more than the rated voltage between any two input terminals, or between

any input terminal and earth ground.

• Do not contact the test lead tips or any uninsulated portion of the accessory.

Failure to observe these warnings can result in severe injury or death.

Electric shock hazard:

Contact with live circuits can result in severe injury or death.

Important Safety Information

• Do not operate with the case or battery cover open.

• Before removing the case or battery cover, remove the test leads (or jaw) from the

circuit and shut off the unit.

Failure to observe these warnings can result in severe injury or death.

• Do not attempt to repair this unit. It contains no user-serviceable parts.

• Do not expose the unit to extremes in temperature or high humidity.

Refer to “Specifications.”

Failure to observe these precautions can result in injury and can damage the unit.

Do not change the measurement function while the test leads are connected to a

component or circuit.

Failure to observe this precaution can result in injury and can damage the unit.

• Unless measuring voltage, current, or frequency, shut off and lock out power. Make

sure that all capacitors are discharged. Voltage must not be present.

• Using this unit near equipment that generates electromagnetic interference can

result in unstable or inaccurate readings.

Using the Features

•

Press to backlight the display. Press again to turn off. The backlight automatically shuts off

after approximately 1 minute.

•HOLD Button

Press momentarily to hold the present value on the display. Press again to return to normal

mode.

•Auto Power Off

The unit automatically shuts off after approximately 30 minutes of inactivity.

To disable this feature, press PEAK, MIN MAX, or while turning the meter on.

•MIN MAX Button

Press momentarily to begin recording the minimum and maximum values of input. Press

momentarily to cycle through the display modes as shown in the table below. The meter uses

its highest voltage or current range for this feature.

Press and hold to exit this mode.

•PEAK Button

Press momentarily to begin recording the minimum and maximum peak values of AC inputs.

Press momentarily to cycle through the display modes as shown in the table below. The meter

uses its highest voltage or current range for this feature.

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 Greenlee CM-1300 is an average-responding meter.

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-1350 is a true RMS meter.

The Waveforms and Crest Factors table shows some typical AC signals and their RMS values.

Waveforms and Crest Factors

*The crest factor is the ratio of the peak value to the RMS value; it is represented by the Greek

letter ξ.

1. Set the selector according to the Settings Table.

2. Refer to “Typical Measurements”for specific measurement instructions.

3. Test the unit on a known functioning circuit or component.

•If the unit does not function as expected on a known functioning circuit, replace the

battery (or batteries).

•If the unit still does not function as expected, send the unit to Greenlee for repair. Refer to

the instructions under the Warranty.

4. Take the reading from the circuit or component to be tested.
