Touch the [ENT] key to display the calibration gas value.
This value must be the zero gas concentration set in Section
7.10.1, "Calibration Setup," earlier in this manual.
To cancel the above, touch the [>] key and [ENT] key together,
then the display returns to "ZEro Y."

OPEn
/0.89
If you touch the [ENT] key, "OPEn" and the currently measured
value are displayed alternately. Open the Flow Setting Unit zero
gas ow valve and adjust the zero gas ow to 600 ± 60 ml/min. To
do this, loosen the valve lock nut and gently turn the valve control
(shaft) counterclockwise.
Check the calibration gas owmeter for conrmation. If the
automatic calibration unit is connected, open the zero gas
solenoid valve, and then the measured value changes to the zero
gas value. When the display becomes stable, proceed to the next
step.
To cancel the above, touch the [>] key and [ENT] key together,
then the display returns to "ZEro Y."

CALEnd
Touch the [ENT] key again to get the measured value to agree
with the zero gas concentration. Close the zero gas ow valve.
Secure the valve lock nut for leakage during measurement.
If the automatic calibration unit is connected, close the span gas
solenoid valve. "CALEnd" ashes during the output hold time. If
"output hold" is specied in the Output Hold setting," it remains as
an analog output (see Section 8.2).
When the preset output hold time is up, the calibration is
complete.

The output hold time is set to 10 minutes at the factory.
If you touch both the [>] key and [ENT] key at the same time
during the preset Output Hold Time, the calibration is aborted and
the parameter code selection display appears.

ENT Basic panel
display
If you touch the [>] key and [ENT] key together, then the basic
panel display appears.
The above “display” is a result of switch operations.
The symbol [
] indicates the keys are being touched, and the light characters indicate “ashing.”
“/” indicates that the characters are displayed alternately.
