7−14. CHECK value
After pressing the key together with the key in the measurement mode, the CHECK
value corresponding to the set value in the function F−11. At the same time, “CHECK” in the
condition display lights on, and the load value corresponding to the set value in the function F−11
is added on the load display value. As for default, 0.3 mV/V has been set.
By pressing the
key together with the key again, the CHECK value will be OFF and
returns to the former condition as it is.
● When the setting of Function F−11 is “00000”, the load display value
will not vary even if the “CHECK” lights up on the condition display.
(Because CHECK is 0.0 mV/V.)
● When the CHECK value is ON condition, the RUN output of open
collector is OFF and RUN LED in the condition display turns off.
7−15. Record place of set data etc.
This instrument records the each data in the RAM and EEPROM as follows.
As the EEPROM is nonvolatile, it is stored semi−permanently.
Also, RAM is kept by the battery. The backup time is about ten years in the room temperature.
1
Data recorded in the RAM
・A/Z data available to clear by A/Z OFF
・ZERO data available to clear by the execution of F−98
・ZERO tracking data available to clear by the execution of F−98
2
Data recorded in the EEPROM
・FUNC data available to initialize by the execution of F−99
・Calibration data available to re−write by re−calibration
・Fine adjustment data of analog output available to re−write by fine adjustment again
・Each set value of the comparator S0 to S4 available to clear by the change of each set value
7−16. Prohibition of calibration
The instrument prepares the setting for prohibition of calibration to prevent from excessive
calibrations. This setting can be made in the Function mode(Related Function F−97).
As for the default, “Possible to calibrate” has selected.
The targets of prohibition are each calibration described in the Chapter 5, and each fine
adjustment on the analog output described in the paragraph 9−1−7 and the paragraph 9−1−8.
When executing the calibration with the set of Prohibition of calibration, the “ER−6” is displayed.
