7. Operating Method
The output interface of this machine is set inside. When using the oscilloscope, please select high input
resistance (1M
Ω
). If the input resistance is 50
Ω
, the data will be incorrect
Please make sure the current measured doesn’t surpass the maximum current. The magnetic core will
saturate. The saturated magnetic core will neutralize the generate waveform during saturation. The
overcharged inrush might cause mistaken degaussing and need to be zero set again.
When power is connected, offset might occur because of the heat generated by the machine. But it will be
stabilized after about 30 min.
Strong Magnetic field like transformer, large circuit, high electricity like wireless will cause deviation
The voltage might deviate because of the surrounding temperature, so please be careful when testing
sequentially
The frequency of the current under test may cause resonance, but this won’t influence the testing.
The position of conductor under test in the sensor will influence the result, so please move the conductor
under test into the center of the sensor.
Push the switch control pole all the way through until the unlock mark disappear. Please make sure the
control pole is locked and the entire structure is closed. If the entire structure isn’t closed, the testing will go
wrong.
If you insert the high potential side of the circuit in high frequency domain, the result might be influenced
by the noise. If it’s necessary, please limit the waveform observer’s frequency domain or insert the low
potential side of the circuit.
When disconnecting the output terminal, please pull out the connector after unlocking. The output terminal
will be damaged if you force to drag the cable out before unlocking
When putting in the output terminal other than BNC terminal, please be careful for the polarity of the
terminal
The continuous maximum input range is the fixed value caused by the machine’s operating heat. Please do
not put in current higher than this value, or the device will be damaged
The continuous maximum input range will change according to the frequency of the current under test. The
probe will be damaged when operate under overcharged current
When the input current continuously surpasses the maximum input range, the self-protection will be
activated by the heating of the sensor and cause wrong output. Please stop the current input and wait for full
cool down before next operation.
The protection circuit will be mistakenly activated by the high temperature even when the continuous
current under test is below the max input.
When the connect input surpass the max input range current and activate the protection function too often,
