Sensor Programming

6. SENSOR PROGRAMMING
®
As all ALMEMO
®
the ALMEMO connector plug, the user does not usually need to perform any
programming. Only if, for example, sensor errors must be corrected or existing
sensors must be scaled or limit values need to be specified the comprehensive
programming options have to be used. It must be considered that standard
sensors are, by a locking mode, protected against unintentional modification
and that the locking level must first be reduced before desired changes can be
performed (see 6.7). All parameters can easily be entered or changed via
keyboard when the corresponding sensor connector is connected and the
function activated (see 5.2).

6.1 Selecting the Input Channel

To query or to program the parameters of a sensor the corresponding input
channel must be selected within the desired function using the key CH▲. If this
is performed within any programming function, i.e. not with the rotary switch
moved to function MEASURE, only the input channel will be changed but not
the selected measuring channel, i.e. the measurement is not being interrupted.
Increase the input channel by:
Decrease the input channel by:

6.2 Selecting the Measuring Range

If users want to program the connectors on their own or frequently change the
measuring range, it is necessary that the locking is cleared (see 6.7) and
special connectors may be required for some transducers (e.g. thermo, shunt,
divider etc., see table).
The selection of the measuring range is performed within the function RANGE
´R´. For activating a channel that has not yet been programmed the locking of
the 1st channel must be cleared for the corresponding sensor. After selecting
the input channel and pressing the key ENTER the abbreviation for the
measuring range flashes in the display. The keys " and # allow to select all
available ranges in the sequence given below. If the key ENTER is pressed and
held it is possible to jump from group to group (group ranges bolded in table). If
the desired range is displayed the programming can be completed by pressing
ENTER once again and the data is transmitted to the connector. All
programming values of the input channel are then cleared.
