14.2 Procedure of External Resistance Calibration
2. Output of current for the resistance measurement
• Do not touch, the power cable, torch, or jig stand while current for the
resistance measurement is being output.
Failure to observe this caution may result in electric shock.
(1) Record the value of parameter C08 in advance since the result of the measurement
is overwritten.
(2) Press the "Record" button for 3 seconds or more.
The constant current is output for measurement of the resistance, and power is sup-
plied to the power cable that is to be an external resistance path.
The conduction lasts for approx. 2 seconds and completes automatically.
After the output, the resistance is measured and its result is stored in the parameter
C08.

Fig. 25 Current Output for Measurement of Resistance
- Press the "Record" button again to stop the current output during conduction, however
NOTE
the resistance is not measured.
- When cable for resistance measurement or the power cable, etc. is not connected, the
ammeter (7-segment LED indicator for current) displays 0 A. Confirm the connection
path.
- when the contact of the cable for the resistance measurement and the joint of the power
cable is insufficient, wrong resistance might be measured. Please confirm not uneven to
measurements repeat this operation ２ and ３ times， whether to do a certain connection.

During electric conduction, outputs the
A.W/S
current of approx 300 A without motor
rotation, and displays blinking voltage
or current on the voltmeter or ammeter.
