Operation

Electric shock hazard:

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

1. Turn the unit ON.

2. See Typical Measurements for illustrations of typical uses.

3. Choose DC or AC measurement by pressing the DC/AC button. For frequency

measurement, press the FREQ./Hz button.

4. Press the DCA Auto Zero button to fully compensate for residual magnetism when making

DC current measurements.

5. 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.

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

6. Take the reading from the circuit to be tested.

7. Press PEAK HOLD to hold the peak measured value on the display ( icon will be

displayed).

Note: Set clamp so that DC current is positive before using PEAK HOLD.

Typical Measurements

Clamp Around Wire

Notes:

• Clamp the jaw around one conductor only.

• Close the jaw completely.

• Center the wire in the jaw for highest

accuracy.

Note: Current flowing through the jaw in the

direction indicated by the arrow produces a

positive reading.

Clamp Around Line Splitter

Notes:

• The Greenlee 93-30 Line Splitter is divided.

One section renders amps; the other renders

amps multiplied by 10.

• Close the jaw completely.

• Center the line splitter in the jaw for highest

accuracy.

Accuracy

Accuracy is specified as follows: ±(a percentage of the reading + a fixed amount)

at 23 °C ±5 °C (73.4 °F ±9 °F), 0% to 75% relative humidity.

See the Specifications section for operating conditions.

Accuracy Table

Value Range Accuracy Overload Protection

Current 0 to 100.0 A ±(2.9% + 0.8 A)

(DC) 100 to 399.9 A ±(1.9% + 0.5 A)
