9. ANALOGUE OUTPUT
For analogue acquisition of the selected measuring point either an analogue
output cable ZA 1601-RK (see manual 5.1.1) without electrical isolation or a
relay trigger analogue adapter ZA 8000-RTA (see manual 5.1.3) with
electrically isolated analogue output can be connected to the sockets
A1(OUT1) or A2(OUT2).
Scaling
It is possible to spread any partial range to the standard output signal of the
three available options 0-2V, 0-10V, 0/4-20mA if the partial range covers at
least 100 digits (e.g. 0-20mA for +200.0 to +1000.0°C). To achieve this the
analogue output-start
and the
analogue output-end
of the desired
measuring range must be entered within the functions
AS
and
AE
(see manual
6.10.7). If the initial value is zero it will remain cleared.

These two parameters, analogue output-start and analogue output-end, are
also stored in the EEPROM of the sensor and can, therefore, be individually
programmed for each channel, i.e. during a manual switch through the
channels an individual scaling is available for each measuring variable.
