F4 Operation
A digital input, F4, is standard on the meter. This digital input is programmed identically to function keys
F1, F2, and F3. The input is triggered with a contact closure to COM, or with an active low signal. During
operation, F4 operates according to the way is has been programmed in the
Advanced Features
– User
menu.
Only STOP Operation Enabled if a Batch is Running.
During a batch process, the only function that can be
performed is the pause/stop functions of the STOP
button; the default programming of the F3 key. No other
functions, including min/max display, manual alarm reset,
or total reset, will function while a batch is running.
Multi-Point Calibration & Scaling
The controller is set up at the factory for 2-point linear calibration. The number of points for multi-point
calibration/scaling is set up in the
Advanced
Features
menu. Up to 32 linearization points may be
selected. See page 55 for details.
Maximum/Minimum Readings
The max & min readings (peak & valley) reached by the process can be displayed either continuously or
momentary:
1. Display briefly by assigning to the digital inputs in the
User
menu.
2. Display continuously by assigning either display to max/min through the
Display
menu.
Changing the programming of the F1-F3 function keys will
disable the default batch operation of these keys, and is not
recommended for batch control applications.
Any of the digital inputs can be programmed to reset the max & min readings.
To display max/min readings continuously:
Assign either display to Max (
d Hi
), Min (
d Lo
), or toggle between Max and Min (
d HL
) every 10
seconds.

of the batch process.
