Output Hold Setting

The "output hold" functions hold an analog output signal at a preset value during the equipment's
warm-up time or calibration or if an error arises. Outputs 1 and 2 can not be set individually. Table
8.5 shows the analog outputs that can be retained and the individual states.

For manual Calibration:
Calibration period starts when you enter a calibration-start screen ("Figure 7.15 Manual
calibration steps"). The calibration period lasts until you end the calibration after the calibration
operations. The mode ends after End key is entered and the preset HOLD TIME elapses.
For semi-automatic Calibration:
Calibration mode starts when you select Calibration on the touch panel or the command is issued
by contact input. The calibration period lasts until the HOLD Time elapses after the calibration
operations.
For automatic calibration;
Calibration period lasts after a calibration is conducted at the time of calibration-start until HOLD
Time (output stabilization) elapses.
