3. Operating environment

1). Operating. Temp：0～+50℃
2). Storage. Temp：-3～+80℃
3). Operation relative humidity：
+10℃～+30℃：85±5% relative humidity（non-condensing） ：
+40℃～+50℃：45±5% relative humidity（non-condensing） 4).
Operating height：0~2000m

4. Operation

1). To make a current measurement, switch on the clamp by selecting the 100mV/A range.
Check that the battery indicator (green) is lit and that the <<OL>>indicator is not lit.
2). Connect the clamp to the oscilloscope. With the clamp closed and without clamping a
conductor, select the highest sensitivity (for example 1mV/cm) on the oscilloscope and 100mV/A
on the clamp, then set zero on the clamp with the thumbwheel in relation to a reference chosen
on the oscilloscope. Zero on the oscilloscope makes it possible to adjust this setting.
3). Select the measurement sensitivities of the clamp and the oscilloscope.
4). Choose the connection method which is the best adapted to measurement on the oscilloscope
5). Note the direction of the primary current by means of the arrow marked on and under the case.
6). Insert the conductor carrying the current to be measured in the clamp and take the
measurement.
7). If necessary, re-check the origin of the graph, with the jaws not clamped around the
conductor, and make the measurement again.

5. Maintenance

For maintenance, please kindly contact the reseller or manufacturer.
Jaw faces: It is necessary to always keep the jaw faces clean. Clean them and

lightly oil them to prevent corrosion. Do not leave the clamp in very damp places, or
directly exposed to water.
Handles and case: Clean with a damp cloth or a sponge, then dry with a cloth or

blow dry with warm air.
To maintain the performance of the clamp, it is advisable to carry out a check

or re-calibration every year.
