Advanced Operation and Programming
In addition to the functions described in Controller
Operation on page 25, the following advanced
operation and display features may be programmed. Configuring these features may disable some
default batch controller features, or make running a batch operation impossible. These functions should
only be used by users who are sure of their need in their application.
Function Keys Operation
During operation, the programmable function
keys operate according to the way they have
been programmed in the
Advanced Features
– User
menu. The following table shows the
default setting for each of the function keys.
Digital Input Operation
Five (5) digital inputs, F4-F8, come standard on
the meter. These digital inputs are
programmed identically to function keys
F1, F2, and F3. The inputs are triggered
with a contact closure to +5 (COM in the
case of F4, see Digital I/O Connections on
page 20 for details), or with an active low
signal. During operation, digital inputs
operate according to the way they are programmed in the
Advanced Features – User
menu.
Advanced Setup and Calibration
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 53 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.
