Measuring units
Digital indicators are applied for readout of level, flow, pressure,
ph etc. The far most used measuring values are pre-printed as
symbols on the enclosed green sheet. The indicators are
supplied with a transparent panel where symbols from the pre-
printed sheet can be put in. Use white transfer letters or a white
pen if your symbol is not enclosed.
On type 531, the label can easily be put in by loosening the
display insertion from the lid. On type 532 and 533 the front
frame can be dismantled. Push carefully on the terminal plugs
on the back of the instrument to push out the front glass.

Adjustment
The indicators have a built-in signal generator for adjustment
and readout of limit values eliminating the need for external
instruments. When adjusting, the indicator must be connected
to an active measuring signal. The measuring signal has no
influence on the adjustment.
When adjusting decimal separator, 0-point and span, only the
switches for decimal separator and one of the switches for
adjustment of 0-point or span can be in the ON position.
Setting of decimal separator position
3 switches for setting of the decimal separator position is found
on the back of the indicator. The following four settings can be
selected:
8
.
8 . 8 . 8 8 . 8
.
8 . 8 8 . 8 . 8
.
8 8 . 8 . 8 . 8
Adjustment of 0-point
The optional values for 0-point is shown in
section "Specifications".
Set the switch "MEASURE" in "OFF" position and the "4 mA
READING" in "ON" position. Set the 0-point with the potentio-
meter to "4 mA READING". Set the switch "MEASURE" back in
"OFF" position, and the instrument is now ready for use.
Adjustment of span
The optional values for span is shown in section
"Specifications".
Set the switch "MEASURE" in "OFF" position and the "20 mA
READING" in "ON" position. Set the 0-point with the potentio-
