S601, S610
For measuring negative pressure, positive pressure, differential
pressure and relative pressure of gaseous media in non-
explosive areas.
This function is only guaranteed when used within the specified
limits –see [Technical data –p. 4]. Any other use is considered
as non-compliant.
! CAUTION
Please observe the following to ensure that the
DMG is not damaged:
–Do not use the DMG in potentially explosive areas, or on people
or animals.
–Note the max. medium and ambient temperatures, see
[Technical data –p. 4].
–Protect the DMG against shocks and moisture.

ZERO (zero point calibration) operating mode
▷In ZERO operating mode, the zero point can be
set at any time and as often as required.
1Press menu button
UNIT (unit selection) operating mode
1Select the unit according to the measuring
mode using the menu button
AUTO (measured value resolution) operating
mode
▷Availability of this operating mode is dependent
on the measuring ranges.
▷In AUTO operating mode, the best possible
display of the measured value is preset
automatically. The resolution is thus adjusted or
reduced as the measured value increases.
▷The desired measured value display can be
preset manually using the menu button , so that
irrelevant digits after the decimal point, for example,
can be masked.
Auto: automatic measuring range selection,
Lo (Low): low measuring range (higher resolution),
HI (High): high measuring range (low resolution).
Min./Max. measured value
1 Press min./max. button .
▷The display shows the minimum measured
pressure value.
2 .Press min./max. button again.
▷The display shows the maximum measured
pressure value.
3 . To delete the min./max. measured value, press
the menu button .
▷The current measured pressure value is displayed again.
Hold function
▷In all operating modes, the measured value can be held
by pressing the pause button ӀӀ .
▷appears in the top left corner of the display.
▷By pressing the pause button again, the measured
value is released.
Display lighting
▷The display lighting can be switched on and off
by briefly pressing the On/Off button .
Switching off
▷Press the On/Off button for approx. 2seconds.
▷Automatic time-dependent switch-off is currently
not implemented.
▷It is recommended that you have the instrument
checked regularly (< 24 months) and that it be
recalibrated regularly if used industrially.
Changing the batteries
▷Approved batteries, see [Technical data –p. 4].
▷The charge status is displayed in the top right
corner of the display.
▷Always change both batteries at the same time.
3 Insert new batteries.
4 Ensure that these are connected with the correct
polarity.
5 Place the cover back on the battery compartment
to close.
6 Dispose of used batteries separately.
