1. Test Method for AIT-series Current Transducers
(1) Wiring method:  (2) Test method:

The resistance connected to the sensor output: 10Ω or else

When the wiring is correct and working normally:
(a) When the sensor does not pass current, the voltage on the resistor R is about 0V
(b) When the device is working normally after power on, the green indicator light is always on
(c) When the sensor passes a DC current, the voltage on the resistor R is:

U = Measured Current / Sensor Turns Ratio * Resistance R

If the output voltage is abnormal:

(a) First use a multimeter to measure the power supply of the sensor and check whether the power supply is wired correctly;

(b) Check whether the running indicator and the power supply indicator are displayed normally.

2. Test Method for HIT-series Current Transducers
(1) Wiring method:  (2) Test method:
The resistance connected to the output terminal of the sensor: 10Ω or else;

When the wiring is correct and working normally:
(a) When the sensor does not pass current, the voltage on the resistor R is about 0V;
(b) When the sensor passes a DC current, the voltage on the resistor R is:
U = Measured Current / Sensor Turns Ratio * Resistance R

If the output voltage is abnormal:
(a) First use a multimeter to measure the power supply of the sensor and check whether the power supply is wired correctly;
(b) Check whether the running indicator and the power supply indicator are displayed normally.

3. Test Method for RIT-series Current Transducers
(1) Wiring method:  (2) Test method:
The output terminal of the sensor is connected to the voltage function of the Agilent meter;

When the wiring is correct and working normally:
(a) When the sensor does not pass current, the voltage on the resistor R is about 0V;
(b) After the device is powered on, when the device is working normally, the green indicator light is always on;
(c) When the sensor passes DC current, the primary current Ip is:
Ip=Kn*Uoutput

If the current is abnormal or the power supply is abnormal:
(a) First use a multimeter to measure the power supply of the sensor and check whether the power supply is wired correctly;
(b) Check whether the running indicator and the power supply indicator are displayed normally.

4. Test Method for IIT-series Current Transducers
(1) Wiring method:  (2) Test method:
The resistance connected to the output terminal of the sensor: 10Ω or else;

When the wiring is correct and working normally:
(a) When the sensor does not pass current, the voltage on the resistor R is about 0V;
(b) When the sensor passes a DC current, the voltage on the resistor R is:
U = Measured Current / Sensor Turns Ratio * Resistance R

If the output voltage is abnormal:
(a) First use a multimeter to measure the power supply of the sensor and check whether the power supply is wired correctly;
(b) Check whether the running indicator and the power supply indicator are displayed normally.
