OFF/RANGE SWITCH
Slide the switch from OFF to either the low or high measurement range. When
either range is selected, the probe is turned on, and the green battery indicator
lights. If the indicator does not light, see Battery and AC Power Adapter and
Battery Installation.
ON INDICATOR
The ON indicator lights green when the probe is turned on. For more information,
see Battery and AC Power Adapter and Battery Installation.
OVERLOAD INDICATOR
The overload indicator lights red if the measured signal is greater than the
selected range capability. Switch the probe to higher measurement range, if
possible, or remove the probe from the circuit.
BASIC OPERATION
Before using the probe a battery or specified power adaptor must be installed.
See Battery and AC Power Adapter and Battery Installation.
WARNING!
Do not clamp the probe onto circuits with voltages greater than 600 VAC (600V
CAT II, 300V CAT III). Personal injury or damage to the probe may result.
Always connect the current probe to an instrument before clamping onto the
circuit under test.
1. Connect the BNC cable (CT3955-100) to the current probe's BNC female
output connector then connect the BNC cable to the oscilloscope's BNC input.
Start by setting the oscilloscope's voltage input channel to DC and the voltage
sensitivity to 0.1 V/div.
2. Move the OFF/Range switch to the low V/A or high V/A position. The green
ON Indictor LED will light. If the green ON Indictor LED does not light, replace
the battery or use included power adaptor.
3. Use the ZERO Adjust to zero or offset the probe output of residual magnetic
DC charges.
4. Connect the probe to the circuit by opening the jaws with the Jaws Opening
Lever and clamping around the conductor. See Figure 2.
