When "CAL Err" appears, a calibration coefficient alarm (alarm 6 or 7) may have occurred.
Press [ENT] key to return to basic panel display. Check the alarm number. Refer to Subsection 12.2.2.2, Alarm 6, or Subsection
12.2.2.3, Alarm 7, remove the cause, and then recalibrate the instrument.
The symbol [
"/" indicates that both are displayed alternately.
(2) To start calibration using an input contact, follow these steps:
• Make sure that Calibration start has been selected in the Input contacts display (see
Section 8.5, earlier in this manual).
• Apply an input contact to start calibration.
(3) To stop calibration midway, follow these steps:
Touch the [>] key and [ENT] key together. The calibration will stop and the output
stabilization time will be set up. Touch the [>] key once again to return to the basic panel
display and the analyzer will be in normal measurement.

Description
Change the parameter code to b11. (Previous operations omitted)
Touch the [ENT] key to display "SA-CAL" (Semi Auto CAL).
Touch the [ENT] key again to open the span gas solenoid valve.
The span gas then flows. "SPAn" and the currently measured
value are alternately displayed. If the "output hold" is set, the
output hold will start at this time.
If the set calibration time elapses, the span gas solenoid valve
closes automatically, the zero gas solenoid valve opens and the
zero gas flows. "ZEro" and the currently measured value are
displayed alternately.
End If the set calibration time elapses, the zero gas solenoid valve
then closes automatically. The ''CALEnd'' flashes until the set
output stabilization time elapses.
If the output stabilization time elapses, the basic panel display
then appears. Output holding will be released.
