and1200Hz respectively.
5.
Press Freq1 key then press the Cal. to start calibration, and the instrument will
output the Low Point current.
Divide the voltage shown on the DMM by 3 (3
Ω
shunt) and use the number keys to
enter the result. Press the ENTER key when complete.
The instrument will show “OK”
after Low Point(A).
6.
Press Cal.
softkey to start calibration 2, and the instrument will output the ML Point
current.
Divide the voltage shown on the DMM by 3 (3
Ω
shunt) and use the number keys to
enter the result. Press the ENTER key when complete. The instrument will show “OK”
after the ML Point(A).
7.
Press Cal.
softkey to start calibration 3, and the instrument will output the MH Point
current.
Divide the voltage shown on the DMM by 3 (3
Ω
shunt) and use the number keys to
enter the result. Press the ENTER key when complete. The instrument will show “OK”
after the MH Point(A).
8.
Press Cal.
Softkey to start calibration 4, and the instrument will output the High
Point current.
Divide the voltage shown on the DMM by 3 (3
Ω
shunt) and use the number keys to
enter the result. Press the ENTER key when complete.
The instrument will show “OK”
after the High Point(A). The calibration date and time will be shown below.
Next, calibrate Freq2, Freq3 and Freq4 in order to complete the current calibration.
