waveforms.
8 Start/stop Click to start/end measurement.
9 Save waveform
Click to save the current
waveform.
2. Turn on the power switch on the current clamp, and the
power indicator lamp will be on.
3. Click the "not connected" button on the screen to start
searching for the current clamp. Click the Bluetooth name of the
current clamp to be connected (the Bluetooth name is the serial
number of the current clamp device) to connect. After the
connection is successful, the screen will display "connected".
4. Ensure that the current clamp is not in use. Press the [ZERO]
button on the current clamp until the reading on the screen is 0.
Notes: The effect of external electric field or geomagnetic field
on the current clamp can be eliminated by using the zeroing
function reasonably to make the measured value more accurate.
Zeroing steps: Firstly, put the clamp head close to the measured
wire, and the current clamp induction will output a voltage (the
interference amount of the external electric field). Adjust the
ZERO button to zero the interference amount, and then clamp the
measured wire, so that the test data will be more reliable.
After measuring the large current, the current clamp will have a
certain amount of residual magnetism in a short time. If it is used
for the small current test immediately, perform zeroing again.
5. Press the trigger to open the clamp head, clamp the wire to
be measured and tap Start measurement button on the screen
to measure.
6. When measuring the voltage, insert one end of the current
clamp test clip into the aviation socket of the current clamp, and
