Alarm Storage (Option)
If the measurement value is within the alarm range, an alarm message is continuously displayed.
When the measurement value is no longer within the alarm range, the alarm message is normally
deactivated. If this is not desired, the instrument can be programmed for alarm storage. This func-
tion stores the alarm message until it is deleted with the ⇑ and ⇓ keys, or with an external signal at
the hold input. Alarm storage programming is described in chap. 5.7 page 19.

Automatic Balancing for Pressure Measurements (Option)
If balancing of the zero point and the final value is frequently required during operation, the measur-
ing instrument can be programmed for automatic balancing (see table on page 13, parameter
st
cod 3, 1
digit).
If this function is activated, automatic balancing is activated by pressing and holding the P key for
2 seconds.
ZEro and a digit blink alternately at the measuring instrument. The input magnitude which corre-
sponds to the value of the blinking digit must be applied to the measurement input. The measuring
instrument automatically balances the input magnitude to the digit, which blinks alternately with
ZEro. The value can be changed with the ⇑ and ⇓ keys, to which balancing is to be carried out.
If the P key is pressed repeatedly, SPAn and a digit blink alternately. The input magnitude which cor-
responds to the value of the blinking digit must be applied to the measuring instrument. When the
P key is pressed again, the new values are stored and remain even in the event of power failure.
Pressure Measurement, Special Case
For pressure measurements with Autocal, automatic balancing is accomplished by pressing and
holding the P key for approximately 8 seconds.
