Switching the HMG unit or measurement
channels OFF/ON doesn't automatically de-
lete the newly set zero point. The following
message is shown when switching the HMG
off and then back on:
"Some channels have a zero offset."
Press OK to retain the zero offset or
"Esc" to delete it.
To determine the extent of a zero offset
which has been set, go to the Settings menu
(OK) and select Zero measurement chan-
nels (OK). This brings up a list of all the
channels which are active. Channels with a
zero point adjustment are checkmarked.
The value of the zero offset is shown on the
right.
Any zero offset is also shown in the meas-
urement channel list by way of a small arrow
in front of the measurement range. To find it,
go to the Settings menu, then Change Set-
tings of Measurement Channel (OK).
There is one exception where the zero offset
is automatically deleted. This happens when
a sensor is connected to the channel and
this sensor has a different measurement
range to the one for which the zero offset
was set. This means that the zero offset is
not retained unless the lower and upper
measurement limit, the number of decimal
places, and the unit of measurement of the
newly connected sensor are identical.
When the zero offset is automatically de-
leted, a message to this effect appears in the
display for two seconds.
