” Calibration”
Select the channel number to configure by pressing the up / down arrows and pressing the
right arrow to select and continue.
The screens allow you to define the “Cal Zero” and “Cal Span” values for any channels that
are configured for 0-1 V, 0-5 V, 0-10 V or 4-20 mA inputs.
Example
A pressure transmitter is connected to channel # 1. The transmitter has a 4-20 mA
output representing a pressure input of 0 - 500 PSI. The “Cal Zero” and “Cal Span”
values would be defined as:
Cal Zero = 0
Cal Span = 500
Note that the “Engineering Units” would be input as PSI in “Channel” configuration
above.

“Alarm Logs”
Selecting the “Alarm Logs” icon will allow you to view any active alarms as well as the history
log for each channel. Select any channel number by pressing the up / down arrows. Then
