Recorder output gas
Here one gas from the four gases is defined which will be output as the analog signal
through channel 1. This is selected through the
PLUS
/
MINUS
keys.
Selecting one of the numbers 1 ... 4 outputs the corresponding gas 1 ... 4 on the
display as the analog signal.
Channel 2 (pin 14 of the I/O port) indicates the gas number by way of a voltage, i.e.
a voltage between 1 V ... 4 V will be present accordingly.
When selecting
AUTO
the leak rate which has the highest value with reference to the
corresponding trigger level is output as the analog signal.
Correspondingly the voltage in channel 2 will differ accordingly.
In the modes "
ERROR
”, "
NOT READY TO MEASURE
” and "
SLEEP
” a voltage of U = 10 V
will be output through channels 1 and 2.
