Reading and Changing the device mode
The sensor can operate in one of the following three modes:
d1.analog measurement
d2.Switch (door) open detector
d3.pulse count
A special mode is the ‘pulse count reset’ mode (d4). When activated, the pulse
count is reset to 0. Afterwards, the sensor will go back to the pulse count
mode.
In order to set the device mode the following steps should be performed:
- Select the appropriate LCD mode: ‘show device mode’
- Push the left button a long time (a few seconds) until the ‘d’ starts to blink
- Push shortly to increment the device mode.
- When you have selected the correct value, leave the device untouched.
It will jump to the ‘show measurement LCD mode’ after a few seconds. At that point the
device mode is stored into the on board non-volatile memory.
