Model: 2023P7
Sensor type: Differential
Operating range: 7bar
Connector Type: Screw connector
Units: mbar / bar / PSI / kPa / inHg/ mHg / inH20 / mH20
Operating Temperature: -10°C to +50°C
Accuracy of Unit Only: +20 to +50°C: 0.10% of RDG +0.10% of FS + 1 LSD
-10 to +20°C: 0.15% of RDG +0.15% of FS + 1 LSD
All ± 1 LSD Digit ( 0.1˚C Low scale; 1˚C High scale )
Negative pressure: 0.3% reading + 0.3% full scale
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 manufacturers 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 2023P is suitable for the measurement of differential 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 IP65 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 Key when the unit is being switched on. This will disable the automatic
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
In order to achieve maximum accuracy, it is recommended to zero the instrument in the orientation it will be used
before taking any measurements.
Ensure both ports are open to atmospheric pressure, If indicated pressure is within 1.25%fs of the factory calibrated
zero, press 0.0 key which will adjust the reading to zero.
Hold Function
To enable the Hold Function, press the “Hold “button, Press again to release the Hold Function.
Hose fitting
The input port(s) on the instrument are designed to accept a hose with 4mm I.D 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. 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.
