Operation manual v46
Display buttons have the following meaning:
WRITE
new calibration value is entered into the memory, old value is irreversibly lost
SKIP
current calibration step is skipped, old value is retained in the memory
EXIT
current calibration is terminated. After this button is pressed, the calibration memory
hold all data (old or new entered) and the calibrator returns to the calibration
menu. It is not necessary to calibrate all ranges; calibration of only selected ranges
is possible by skipping the ranges which do not need to be calibrated.
Moreover, the display shows the range which is being calibrated (RANGE), and the value to be set at the external
standard multimeter (VALUE).
Setting the new calibration data
Use
,
,
,
cursor buttons to set such main data on the display, when the output signal measured by external
standard multimeter reaches the required calibration point. When the standard output value is reached, press
“WRITE” to write new calibration value to the calibration memory. If you press “SKIP” button, the calibrator
ignores the new value and old value is retained. After you press “WRITE” (or “SKIP”), the calibrator moves on
to the next calibration point.
The procedure is repeated for all calibration points of the selected function. If you press “EXIT” button before
completing the calibration, the calibrator returns to the calibration menu.
Termination of calibration
The calibration can be terminated in the following cases:
•
complete calibration has been performed, new calibration data have been entered, the program has returned
to the calibration menu,
•
calibration of selected function has been performed, new calibration data have been entered, the program has
returned to the calibration menu,
•
calibration of selected range(s) of selected function has been performed, new calibration data have been
entered, the program has returned to the calibration menu,
•
the calibration has been started but no calibration data have been entered, the program has returned to the
calibration menu after “EXIT” display button has been pressed,
