Changing The Units; Selecting The Measuring Range - Ahlborn ALMEMO 2590-2A Operating Instructions Manual

13. Sensor programming
Function
Zero-point correction:
Gain correction:
To switch on and off press :
Once the scaling values have been programmed and the actual measured value
thus modified the correction arrow appears indicating the measured value status
(see 9.2).
To reach maximum accuracy multi-point calibration of sensors is now

also possible - with option KL (see 13.11).

13.8 Changing the units

For each measuring channel the default units for the measuring range can be
replaced with any two-character units; (see Manual 6.3.5). All upper-case and
lower-case letters, special characters °, , %, !, [, ], *, -, =, ~ and space (_) can
be used. The units are shown as two characters after the measured value or
programming value.
To change the units use the function:
If you enter °F as units the temperature value will be converted automat-

ically from degrees Celsius to degrees Fahrenheit. If you enter !C cold
junction compensation will be disabled. If you enter the appropriate two
characters the following units are generated automatically; for mls enter
ms , for m3lh enter mh , for Wlm

13.9 Selecting the measuring range

If you want to program the connectors yourself or if you often need to change
the measuring range you will have to disable the locking mode for the connect-
ors in question by setting the locking level to 0 (see 13.4); please note also that
for certain transducers a special connector is required (e.g. thermo, shunt, di-
vider, etc., see the table). To activate a new measuring channel first press
<MALL> to activate all channels, then select the required input channel (see
13.1), and then enter the measuring range. When the input for the new meas-
uring range is confirmed all programming values for that input channel will be
deleted.
Function - Measuring range selection
To accept the selection of all possible measuring channels press
To deactivate a channel press
To reactivate a channel press
Programming the range is as for data input (see 9.5 )
In the input window all the abbreviations listed in the following table appear
one after the other :
