Press PROG once more: The new value will be memorised. This is
indicated by 3 dashes "---" appearing for a few seconds. Programming
is now complete and standard operating mode will be automatically
selected.
Programming can be terminated at any time by hitting the RESET key. In
this instance, only such changes are accepted that have been acknowl-
edged by appearance of "---". Otherwise, previously set values remain in
effect.
2.5.2 Verification of programmed settings
(see also appendix A)
Short hitting of the PROG key initiates "Pro" to appear at the display,
followed by all current settings in consecutive order, where:
-A- Low end of scale
-E- High end of scale
dP Decimal point
InX Input signal
OuX Output signal
-d- Damping
dxx Reference of damping
-b- At digital interface: baud rate setting
Indication can be terminated at any time by hitting the RESET key. (see
also 2.7)
2.5.3 Compensation of zero offset
Despite careful calibration, the instrument may indicate a zero offset in
operation. This may be caused by a static head acting on the transmitter
or other process conditions. Preferably this should be compensated by
shifting the zero signal of the transmitter. If this cannot be accomplished,
true indication can be achieved by means of shifting low end and high
end indication correspondingly as per examples below.
