Section 11 Manual Calibration
After the power is turned on, the main unit will read the calibration value automatically. This action makes the setting of each amplifier by
reading calibration values that were recorded on a back-up SRAM.
These values can be rewritten and updated by performing manual calibration in <Calibration> of <SYSTEM MENU>. In this case of calibration,
internal recording of each input range and sampling frequency is performed, and then the offset value and gain value are calibrated by
internal reference voltage to update the calibration value to be recorded on a back-up SRAM.
Rewriting the Calibration Value by Manual Calibration
W
hen precision is required in particular or the temperature is entirely different from the normal temperature (ie:-10
℃ 、
+50 ), manual
℃
calibration must be performed before measuring. In any case, we also recommend you to perform periodical manual calibration about
once every 6 months to maintain a higher level of measurement precision.
Executing manual calibration
1.
Press [MENU] to show <SYSTEM MENU>, and move cursor to <Calibration>.
2.
Press [MENU] to show the confirmation menu. If you press [ENTER], the system will
start calibration. If you press [ESC], the system will return to <SYSTEM MENU>
without performing calibration.
3.
Press [ENTER] to perform calibration.
The massage (see figure on the left) will appear during calibration.
And the REC LED blinks red.
4.
When the calibration is finished, the system returns to <SYSTEM MENU>.
