10.8  'dA.Lo': Display at zero output (output scaling)

Enter the display value at which the output should have 4 mA (or 0 V).
The value range is depending on the selected measuring function (Func) and range (rAnG).

10.9  'dA.Hi': Display at maximum output (output scaling)

Enter the value at which the output should have 20 mA (or 1 / 10 V).
The value range is depending on the selected measuring function (Func) and range (rAnG).

10.10   'Unit' with Temp-arrow: Temperature unit

Temperature unit: All referring settings and displays are done in this unit.
Choice between °C and °F (ex works: °C)

10.11   'OFFS' with Temp-arrow: Offset of temperature measuring

The offset of the measuring will be shifted by this value, the input is in °C. Calculation: see below.
Max. input range: -5.0...5.0 °C or 'oFF' (= 0.0°) (factory setting = off)

10.12   'SCAL' with Temp-arrow: Scale correction of temperature measuring

The scale of the measuring is changed by this value. Calculation: see below.
Max. input range: -5.00...5.00 or 'oFF' (= 0.00) (factory setting = off)
The adjusting of the temperature by means of offset and scale is intended to be used to compensate devia-
tions of the measuring. It is recommended to keep the scale correction deactivated (“oFF”). The display
value is given by following formula:

Temperature display = measured value - offset

With a scale correction (just for calibration laboratories, etc) the formula changes:

Temperature display = (meas. value - offset) * ( 1 + scale correction/100)

After pressing key 1 again, the instrument will restart (display 8888).
