Note: Do not tighten fittings attached to the pressure ports to a torque
greater than 2Nm otherwise the pressure seals may be damaged.
HAND PUMP OPERATION (if applicable)
Use the T piece to connect the hand pump to the instrument's
port and to the equipment being tested. Exhaust the system by
turning the release valve on the hand pump anti-clockwise and set
the fine adjustment threaded piston to mid range.
Close the release valve and apply pump action to the hand pump
piston to generate the required approximate pressure. Fine
adjustment of the desired pressure can then be made by rotating the
threaded piston. The release valve may be used to vent the system.
Note: The hand pump is capable of generating 7bar max. It is,
therefore, essential that extra care is taken not to over-pressure the
instrument.
A pump must not be used on models 2000P, 2020P and 2080P

SMOOTHING MODE
Press = key and the instrument continuously averages the last four
measurements to give a more stable reading on the display. Press
key again to return to normal measurement.
UNITS OF PRESSURE
Press key to select required units of pressure. Chosen units will
be saved when the instrument is switched off.
Please refer to the table on the back page.
The 20x0P 0-25mbar instruments cannot show the µbar or mmHg
symbols on their displays. When switching the units on they are
reading in µbar and so show no unit symbol. Pushing the autorange
button will put the unit into mbar and show the mbar symbol. When
reading in mmHg only the symbol Hg will show on the display.
This function will not operate while in store mode.
