OTT PLS - Setting Measuring Time; Setting 4-20 mA Lower Limit; Setting 4-20 mA Upper Limit

Command Response Description
Caution
This command overwrites any set offset value.
Example
Measured value = +2.100 m
reference value = +1.500 m
output = +1.500 m
(offset calculated by the OTT PLS and applied to all other
measured values = +0.600 m)
Note
If the unit is changed afterwards (aOSU<value>!), round-
ing errors of ±0.001 are possible.

Read out measuring time
a – Sensor address
<value> – bb
b – numbers
Input/output is without leading zeroes!
Value range: 1 … 60 [s]
Factory setting = 2 [s]
Note
If measuring time is ≥ 3 seconds, <value3> and
<value4> appear aditionally in the response to an aD0!
command. With 1 second measuring time, the response is
identical to 2 seconds measuring time.
