Operating Manual dV-2 - 3 -
NOTES
1) The functions and units can also be called up by keeping the Select-key de-
pressed. Releasing the key enables the displayed function or unit to be activated
with the enter-key.
2) If the selected function or unit is not activated within 5 seconds with the enter-
key, the dV-2 returns to the measuring mode without changing any settings.
3) Turning the dV-2 on and off (or a battery change) does not influence any of the
previous settings.
4) If a pressure can not be represented on the display, UFL (underflow) or OFL
(overflow) appears on the display.
5) If the actual pressure goes beyond the measuring range of the instrument, the
last valid pressure value starts flashing on the display.
INSTALLATION
Screw the dV-2 into the pressure port and tighten using the hexagon of the transdu-
cer (pressure connection). If necessary, adjust the manometer housing.
The instrument may only be installed and operated by authorized qualified personnel.
BATTERY CHANGE
Carefully pull forward the frontsided cover by hand. Pull the battery out of the battery
holder and insert a new one (type CR 2032 Lithium 3,0 V). Snap the cover back into
its place.
RANGES / CALIBRATION
The factory setting of the zero for the ranges ≤ 31 bar absolute is at 0 bar absolute.
For sealed gauge pressure measurements, activate SET Zero at ambient pressure.

absolute.
