6. Description of the parameters
1 Device identifier
The device identifier is included in the output protocol to identify the data values. The first output string is
assigned with the device identifier. For every following string the device identifier is increased by 1 (see
chapter 7). It is recommended to set the device identifier to 0 .
Value range: 0 to 9999 (default: 0)
Example:
o if Device identifier is adjusted as 0:
I000000000000000000000409;
I0100-999000002510000042A;
I020000100013-862-8860430;
o if Device identifier is adjusted as 3:
I03000000000000000000040C;
I0400-999000002510000042D;
I050000100013-862-8860433;
More details regarding the output strings you can find in chapter 7.
2 Meas. Interval
The measurement interval controls the time for the measurements. For permanent monitoring it is
important, not to set a to short interval. The measurements are performed using a measurement battery. A
to short measurement interval will prevent the battery from charging and the measurement will be invalid.
The recommended interval is 10 minutes (600 s).
Unit: [s]
Value range: 5 to 13980
(default: 600; values greater than 240 are rounded to multiples of 60)
3 Output time
The output of the data is either performed directly after the measurement or the data strings are requested
by a exclamation mark sent via the RS-232 interface.
