Measuring instruments are programmed at the factory as shown on the serial plate. If programming
is enabled, instrument settings can be changed:
a) with the three keys at the front panel and
b) via the serial interface if included.
Press the keys P and ⇑ simultaneously to initialize programming. Parameter identification and the
corresponding value blink alternately for menu commands. The longer the key remains pressed, the
faster the value changes. Storage of the selected value only occurs after the subsequent parameter
has been called up (P key).
If the programming sequence is to be interrupted prematurely, the keys P and ⇑ must be pressed
simultaneously after storage with the P key has occurred.
If no activation of keys in the programming mode occurs for a period of 1.5 minutes, the measuring
instrument automatically returns to the normal operating mode. This function is suppressed for pres-
sure measuring instruments. Complete programming can be carried out via the serial interface, if
available.
5.2 Measuring Range Adjustment
The measuring range can be adjusted in two different ways:
• By applying the measurement magnitudes for measuring range upper and lower limits, and stor-
ing these to the parameters ZerO and SPan (via hCA = hardware calibration).
• By defining an offset magnitude and a multiplier with the parameters OFSt and SCAL
(via PCA = software calibration).
5.2.1 Measuring Range Adjustment with hCA
Apply the value to the measurement input, which corresponds to the measuring range lower limit.
Select parameter ZErO and set the value, which corresponds to the measuring range lower limit.
Apply the value to the measurement input, which corresponds to the measuring range upper limit.
Select parameter SPAn and set the value, which corresponds to the measuring range upper limit.
Store the values with the P key. The measuring instrument automatically determines offset and mul-
tiplier, and stores the corresponding values.
Attention: If, during calculation of offset or multiplier, values occur which do not lie within the setting
range, the error message Err1 is displayed briefly and the measuring instrument immediately exits
the programming mode (e.g. SCAL => 19,999).
5.2.2 Measuring Range Adjustment with PCA
Offset and multiplier are set digitally for measurement range adjustment with PCA.
Offset Calculation (OFSt)
The offset value is the number of digits, by which the display for the "normal" zero point is displaced.
The offset value is calculated according to the following equation, without taking a decimal point into
consideration:
SA x (ME – MA)
Offset = MA

--------------------------------- -
SE SA
MA = Measuring range lower limit (display range lower limit)
ME = Measuring range upper limit (display range upper limit)
SA = Signal range lower limit (input range lower limit)
SE = Signal range upper limit (input range upper limit)
