DIP Switch Functions
The table below is also printed on the protection board:
0505-285 Figure 22 DIP Switch Functions
1: Analog output test on/off
If you turn the switch to on position (up), you can force the outputs to
states 4 mA, 12 mA and 20 mA by pressing buttons Up and Dn on the
cover. Outputs return to normal mode when switch is turned down.
2: Calibration Disabled/Enabled
The EEPROMs are write protected. If this switch is in the disabled
position (down), it does not allow any calibrations or scalings.
3 and 4: Calibration rh, t, analog
With these combinations you can perform relative humidity,
temperature or analog output calibrations with a multimeter or with the
transmitter display unit. Turn the DIP switches to the desired position
according to the table printed on the protective cover.
NOTE Keep this switch always in the disabled position during normal use of
the transmitter.
