GSafety Information

To ensure safe operation and service of the meter,

follow these instructions. Failure to observe warnings can

result in severe injury or death.

QAvoid working alone so assistance can be rendered.

QTo enhance safety, test leads should be disconnected from

instrument when not in use

QDo not use test leads or the clamp meter if they

look damaged

QDo not use the clamp meter if the tester is not operating

properly or if it is wet.

QUse the clamp meter only as speciﬁed in the instruction

card or the protection provided by the clamp meter may be

impaired.

QSpecial precautions are necessary when operating in

situations where exposed live parts at dangerous voltages may

be encountered. Personal protective equipment (not supplied

with the instrument) should be used.

QThe test leads should be disconnected from the instrument

when making a current measurement.

QUse caution with voltages above 30 V AC RMS, or 60 V DC.

These voltages pose a shock hazard.

GCaution: If the meter is used in the vicinity of equipment which

generates electromagnetic interference, the display may become unstable

or the measurements may be subject to large errors.

Zero

Using the Relative mode (REL), a stable value can be stored, the instrument

zeroed at that point, and then any variation from that value is displayed as

a direct measurement relative to the stable value.

2. Make a measurement and then press the ZERO button.

REL: Meter stores the measured value after pressing the

ZERO button.

3. REL (ﬂashing): The meter saves the offset value. Present

value is displayed.

1. Normal: Press and hold ZERO for > 2 seconds to return

to normal operation and cancel the offset value.

Input Impedance: ≥1MΩ// less than 100pF.

AC Conversion Type:

AC Conversions are ac-coupled, true rms responding, calibrated to the rms

value of a sine wave input. Accuracies are given for sine wave at full scale

and non-sine wave below half scale. For non-sine wave add the following

Crest Factor corrections:

For Crest Factor of 1.4 to 2.0, add 1.0% to accuracy.

For Crest Factor of 2.0 to 2.5, add 2.5% to accuracy.

For Crest Factor of 2.5 to 3.0, add 4.0% to accuracy.
