7.1.6 Calibration Cycle
All input types are factory calibrated. Should it be required, calibration should only be done by
experienced personnel. If this cycle is accidentally accessed do not touch the
or
keys. Just go through
all cycles until the display shows the main or operation menu.
PARAMETERS
PROMPT PARAMETER DESCRIPTION
In.lo(
Input Low Calibration - Sets the Process Variable low calibration (offset). Several key
strokes at
or
might be necessary to increment one digit.
In.ki(
Input High Calibration - Sets the Process Variable span calibration (gain).
Ov.lo(
Analog Output Low Calibration - Sets the analog current output low calibration
(offset).
Ov.Ki(
Analog Output Span Calibration - Sets the analog current output high calibration
(span) of the analog output (20mA).
(J lo
Cold Junction Calibration - Allows the user to adjust this calibration directly in
degrees, of temperature in the indicator terminals.
k.type
Hardware Type - These parameters adapt the software to the hardware available
and should not be changed by the user.

7.2 Serial Communication
The indicator can be supplied with an asynchronous RS-485 digital communication interface for
master-slave connection to a host computer (master). The indicator works as a slave only and all
commands are started by the computer which sends a request to the slave address. The addressed unit
sends back the requested reply. Broadcast commands (addressed to all indicator units in a multi-drop
network) are accepted but no reply is sent back in this case.
