Note: FS=Full Scale LSD= Least Significant Digit (Full range of the unit to be used for both low & high scale calculations)
Particular care should be taken not to over pressure the device as this may rupture the sensor membrane. This is
not covered by the manuafacturers warranty.
Note: The differential/gauge instrument will only measure relative pressures i.e positive pressure applied to the
positive port or negative pressure applied to the negative port.
Instrument Application
The 2025P is suitable for the measurement of absolute pressure.
Instrument Operation
The instrument requires two AA or equivalent cells. These are not supplied with the unit.
When the batteries require changing the following symbol will be displayed:
Please ensure the screws holding the battery compartment are firmly tightened when inserting or replacing batteries
to ensure the IP67 rating is maintained.
Press ON key to turn unit ON. Press OFF key to turn unit OFF.
The unit will switch OFF automatically after 12 minutes, unless any key is activated.
To disable automatic switch off, hold
switch-off function until the unit is switched off.
Out of Range
If pressure exceeds the scale range Out will appear on the display.
Zeroing Absolute
First turn unit ON, press and hold the HOLD key until the current offset is displayed (900). By pressing HOLD key
again, any previously stored offset is cleared, returning the unit back to the original factory settings.
To enter a new offset or to change the existing offset: "Hold" to increment or "2" to decrement the offset, press
SMOOTH key to accept and permanently store this new offset. Up to maximum offset of ±20mbar. Pressing off in
this procedure will retain the previously stored value.
Hold Function
To enable the Hold Function, press the "Hold"
Hose fitting
The input port(s) on the instrument are designed to accept a hose with 4mm internal diameter and 1mm wall. The
hose is fitted by unscrewing the clamping nut, sliding the hose on to the stepped shaft and refitting the nut.
WARNING – Maximum torque is 2Nm, only tighten the clamping nut and not fitted port otherwise this may sheer
the port which is not covered under warranty.
Smoothing mode
Press ═ key and the instrument continuously averages the last four measurements to give a more stable reading on
the display. Press ═ again to return back to normal settings.
