Calibration points
Each function the calibrator has assigned fixed calibration points which have set during the calibration.
Go next requested calibration point. New calibration value saved immediately when
ENTER button rotary button pushed for new value confirmation.
Note: When resistance points are calibrated two-terminals way connection the calibrator tostandard
ohmmetershouldbeapplied. s. When only some calibration points are changed, all other non
changed calibration points are stored with original data. Having selected the required function calibrated, press the rotary button ENTER
button enable the calibration value right column for editing.5 kQ.
• When built mA-meter calibrated, connect current requested valuefrom standard unit and

Selection and setting ofcalibration point
After the calibration menu displayed, one partial calibrations can selected.
Both complete and partial calibration possible. 15Vhas tobeapplied.
• Connect RCL standard meter when capacitance calibration point beingcalibrated andwrite down
new resistance value.
• Measure the resistance value using standard ohmmeter when resistance segment calibrated and write
down new resistance value. Calibrator returns the
