10 GOSSEN Müller & Weigert
Press the P and
⇑
keys simultaneously in order to enter the programming
mode. The parameter designation and the corresponding value blink alter-
nately. The longer the arrow key is pressed and held, the faster the value is
changed. The currently displayed value is not saved until the next parameter
is selected by pressing the P key.
Range matching for 0 / 4 – 20 mA and for Pt100 sensors depends upon the measuring
module, and may only be selected if the corresponding measuring module is utilized
(see specifications on the serial plate).
5.1
Display Brightness
Display brightness can be adjusted with the “bri” parameter. Brightness can
be set within a range of 0 to 7. It is set to a default value of 5 at the factory.
5.2
Measuring Range Matching for 0 – 20 mA and 4 – 20 mA
The parameters AA and AE allow for the entry of a display range without any
additional calibration.
5.3
Measuring Range Matching for Pt100 Temperature Sensor
This selection allows for the display of temperatures in either ˚C or ˚F, and
determines whether 2/4-wire or 3-wire connection is used for the temperature
sensor.
5.4
Measuring Range Matching with HCAL (hardware calibration)
This selection allows for adjustment through the use of a calibrator. The input
quantities for the lower and upper measuring range values must be applied to
the measuring instrument’s input during adjustment.
Apply the value which corresponds to the lower measuring range value to the
measurement input. Select the ZErO parameter and enter the value which
corresponds to the lower measuring range value.
Apply the value which corresponds to the upper measuring range value to the
measurement input. Select the SPAn parameter and enter the value which
corresponds to the upper measuring range value.
Save the selected values to memory with the P key. The measuring instru-
ment automatically calculates offset and multiplier, and saves these values to
memory.
Attention: If values which lie outside of the setting range result from the calcu-
lation of offset or multiplier, the message ErrP appears and the incorrect entry
blinks (e.g. SPAn).
