6. SENSOR PROGRAMMING
As all ALMEMO
®
instruments contain the whole sensor programming stored in
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 if the function is activated (see 5.2) and when the corresponding
sensor connector is connected.
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 M▲. If this is
performed within any programming function, i.e. not in function MEAS. VALUE,
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: (programmed channels only)
M ▲
Decrease the input channel by: press and hold (approx. 1 sec.)

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 long
pressing the key 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 is pressed
▲
PROGR
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 once again and the data is transmitted to the connector. All

programming values of the input channel are then cleared.
