3.3.10 Calibration/Hold Timer Setup
This Calibration Timer lets the operator adjust the time the instrument
purges the calibration gas prior to actually starting the calibration computations.
The Sample timer lets the operator adjust the time the instrument purges sample
gas after finishing a calibration before it lets the analog outputs and display track
the change in concentration.
This function and the TRACK/HOLD feature will prevent false alarms
while performing remote or autoscheduled calibrations. These functions are not
applicable if the calibration is initiated through the front panel. To enter the
Calibration/Hold Timer function, you must:
1. Enter the System menu:
DIG_FILT SELF-TEST
PWD LOGOUT MORE
2. Using theUP/DOWN switch, select MORE and press Enter:
The Second System screen appears:
AUTOCAL HMGNZR TRACK
CAL-HOLD-TIMER MORE
or
AUTOCAL HMGNZR HOLD
CAL-HOLD-TIMER MORE
3. Select with the UP/DOWN switch CAL-HOLD-TIMER,
and press the Enter key to access this function menu:
Calbrt hold: 3 min
Sample hold: 1 min
The calibration hold time is set on the first row, while the sample hold
time is set on the second row. To select one or the other, use the Right or
Left keys. To modify the time of either timer, use the Up or Down keys.
The time is in the minutes.
3.3.11 Analog 4-20mA Output Calibartion
This function will let the operator calibrate the 4 to 20 mA analog output to
match the display reading. A DMM configure as a DC ammeter is needed. The
DMM should be connected across the output terminals of the 4 to 20 mA output
to monitor the output current. To enter the 4 to 20 mA output adjust function,
you must:
1. Enter the System menu:
