Advanced Operations
LOGIC
Default value: DIRECT
Sets the relation between input state and output level.
The menu item is displayed if SET FUNCTION is set to DIGITAL.
DIRECT
If the input contact is closed the output level is LOW respectively if the input contact is open the
output level is HIGH.
REVERSE
If the input contact is closed the output level is HIGH respectively if the input contact is open the
output level is LOW.
SCALE 0 mA/4 mA
Default value: 0–20 mA
Sets the input current range either to 0–20 mA or 4–20 mA.
SET HIGH VALUE
Default value: 20
Sets the value of the output value when the input current is 20 mA.
SET LOW VALUE
Default value: 0
Sets the value of the output value when the input current is 0 mA (0–20 mA scale) or 4 mA
(4–20 mA scale).
ON ERROR MODE
Default value: OFF
An error is reported when input current is out of range (this can be 0–20 mA or 4–20 mA).
When set to “OFF” no error will be reported even if the input current is out of range.
0 mA Substitute value is 0 mA in case of error.
4 mA Substitute value is 4 mA in case of error.
20 mA Substitute value is 20 mA in case of error.
OFF No substitute value is used to replace the measured value in case of an error.
CONCENTRATION
Displays the calculated concentration depending on the input current and the scaling which is set
in the SET LOW VALUE and SET HIGH VALUE menu.
LOG INTERVAL
Default value: 10 minutes
Sets the interval for logging the displayed value into the data logger.
Options: OFF, 5min, 10min, 15min, 20min, 30min
VERSION Displays the software version number
LOCATION Displays the current location
