In the first current input zero mode, the first display will show “1CRZ”.
The second screen will display the measured instantaneous current
from the input. The third display will display the offset value causing
display 00.00 at no current.
Adjust UP and DOWN menu buttons until the value displayed in the
second screen is correct.
When the value is correct then press SET button. The unit will switch
to second current input zero point calibration.
In the second current input zero mode, the first display will show
“2CRZ”. The second screen will display the measured instantaneous
current from the input. The third display will display the offset value
causing display 00.00 at no current.
Adjust UP and DOWN menu buttons until the value displayed in the
second screen is correct.
When the value is correct then press SET button. The unit will switch
to first current input sensitivity calibration.
In the first current input sensitivity calibration mode, the first display
will show “1CUR”. The second screen will display the measured
instantaneous current from the input. The third display will display the
calibration coefficient (high 4 digits only)
Adjust UP and DOWN menu buttons until the value displayed in the
second screen is correct.
When the value is correct then press SET button. The unit will switch
to second current input sensitivity calibration.
The second current input is internal and makes a more precise
measurement in low currents. The switching between two internal
inputs is automatic. Between -10mV and +10mV the sensitive input is
used. Above this signal amplitude the normal input is active.
In the second current input sensitivity calibration mode, the first
display will show “2CUR”. The second screen will display the
measured instantaneous current from the input. The third display will
display the calibration coefficient (high 4 digits only)
Adjust UP and DOWN menu buttons until the value displayed in the
second screen is correct.
When the value is correct then press SET button. The unit will switch
to Vin voltage calibration.
