8.3 HOW TO CLEAR HISTORY DATA
Clearance of various logs after the Assys are replaced
Besides adjustment data, data on accumulated power-on time and logs on defective parts of the product are backed up.
Some of those data must be cleared after the Assys are replaced for service.
Clearance of those data can be performed in the ETC layer of the Factory menu or with RS232C commands.
Notes: • As the pulse-meter count is used for each correction function, the log must be cleared when the panel is replaced.
• After you clear the log, the unit must be turned off then back on again to reflect the cleared data for each correction
function. If any adjustment is required after clearing the log, be sure to turn the unit off then back on again before
adjustment.
