Analog Output Tests

The HMT100 Humidity and Temperature Transmitter has a built-in
software function for testing the analog outputs. To test the outputs,
do the following:

1.

Make sure the transmitter is not in adjustment mode.

2.

Press the 75 % adjustment button (see Figure 14 on page 24).
This sets the output current/voltage level to the middle point of
the selected output range (specified when ordering the product).
The output stays at this level for about 30 seconds after pressing
the 75 % adjustment button.

Examples:

If you have specified 4...20 mA analog output range, pressing the 75
% adjustment button will set the current output at 12.0 mA for about
30 seconds.

For analog output range 0...1 V, pressing the 75 % adjustment button
will set the voltage output at 0.5 V for about 30 seconds.
