The display range of the input signals is from 0.0 to 999.9. Both input signals can be
scaled freely within this range by editing the minimum and maximum displays
(DispMin/DispMax).
• The minimum display is correspondent to a signal of 4 mA.
• The maximum display is correspondent to a signal of 20 mA.
Calibration of Analog Input Signals
The route for calibration of Analog Input 1 is Tools menu\Service (Password level 1: 9490)
\Analog in/out settings\Analog input 1.
This procedure should usually only be relevant after reloading the factory settings. The
calibration of analog input signal is carried out in one of the following ways:
Option 1: Input of tested values
• Select ZeroCalCnt and key in the value according to the ZeroCalCnt value in the Test-
ing & Configuration Sheet attached to each specific monitor. Press to save. The
screen will automatically come back to the Analog setup Ai01 screen.
• Select SpanCalCnt, and key in the value according to the value in the SpanCalCnt val-
ue in the Testing & Configuration Sheet attached to each specific monitor. Press to
save.
Option 2: Manual calibration
Do the manual calibration of analog signal only if the analog signal does not function
properly with the input of the tested values (Option 1).
The manual calibration of analog input signal requires you to go back and forth between
the Analog setup Ai01 screen and the Main Menu.
For zero calibration:
• Simulate a current of 4 mA to Analog Input 1. For passive input signal, connect to
terminal INPUT connection 1 & 3. For active input signal, connect to terminal INPUT
connection 1 & 8.
• Select ZeroCalCnt and adjust the value in ZeroCalCnt until value of analog input Ai01
in the Main display equal to the MinDisp value. Then save the new value of Zero-
CalCnt.
