3.3.9 Hold/Track Setup
The 5000BF has ability to disable the analog outputs and freeze the display
while undergoing a scheduled or remote calibration. The 5000BF will track
changes in the concentration if calibration is started through the front
panel. To setup this feature, the operator must:
1. Press the System key to start the System function:
DIG_FILT SELF-TEST
PWD LOGOUT MORE
2. Using the Right or Left arrow keys, select MORE and press
Enter. The Second System screen appears:
AUTOCAL FILSOL TRACK
CAL-HOLDER-TIMER MORE
or
AUTOCAL FILSOL HOLD
CAL-HOLD-TIMER MORE
3. The option on the right of the first row can be set to TRACK
or HOLD by using the UP or Down keys. By selecting the TRACK option,
the analog outputs are enabled and with the display will track the concentra-
tion changes while the instrument is undergoing scheduled or remote calibra-
tion (either zero or span). By selecting the HOLD option, the analog outputs
and display are disabled and will not track the concentration changes while
the instrument is undergoing scheduled or remote calibration (either zero or
span). In the HOLD option, the analog outputs and display will freeze on
the last reading before entering calibration.
The analog outputs are both 0 to 1 volt outputs and both 4 to 20 mA
outputs.
3.3.10 Calibration/Hold Timer Setup
This Calibration Timer lets the operator adjust the time thee instrument
purges the calibration fluid prior to actually start the calibration computa-
tions. The Sample timer lets the operator adjust the time the instrument
purges sample fluid after finishing a calibration before it lets the analog outputs
and display track the change in concentration.
