3.3.9Hold/Track Setup
The 5000BF has ability to disable the analog outputs and freeze the display while undergoing a scheduled or remote calibration. The5000BFwilltrack 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:

or
AUTOCAL FILSOL HOLD
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.
