6.3 Changing the Dimension
Each measuring channel allows to replace the standard dimension of the
measuring range by any other dimension that has two digits (see manual
6.3.5). In addition to all capital and normal letters, the characters
,
Ω
, %, [, ,
], *, -, =, ~ and spaces (_) are available. The dimension is indicated by two
16-segment characters that are indicated following the measuring and
programming values.
The
change of the dimension can be performed within the function MEAS.
VALUE, DIM by pressing the key
ENTER
. The first character of the dimension
will flash in the display. It can then be changed by using the keys
▲
and
▼
.
When the first character is selected the key should be pressed and the
▲
same procedure will be performed for the second character. When the desired
dimension has been set the programming can be completed by the key
ENTER
.

6.4 Limit Values
Two limit values (MAX and MIN) can be programmed for each measuring
channel. The exceeding of the limit values is handled as a fault, similar to the
exceeding of the measuring range limits and sensor breakage. The arrow
ALARM will appear in the display and the alarm relays will respond and the
alarm values will be provided as output during the measuring cycle (see
manual 6.3.9).
