5.2 LED commands

NOTE

If the transmitter has a display/keypad cover, the LED

commands cannot be used.

LED commands can be used to operate the transmitters in the field. These

commands can be used in humidity and temperature calibration and calibration

of the analogue outputs.

Open the housing and press any one of the three press switches. The LEDs

will light up for 2...3 seconds.
