FIRST TIME USE
Before using the Manometer the first time ensure that the
user-defined settings have been configured (see page 5),
and that the meter has been calibrated (see page 7)
Page 3
INTRODUCTION
This Manometer is ideal for measuring gauge pressure and
low differential pressure in clean rooms, test and balance,
medical equipment, HVAC, pneumatic
systems and computer peripherals.
Features a user-friendly interface with a large backlight
display, automatic data logging, measurement of single
and multiple points and a tripod mount.
The RS232 port, cable and software enable
communication with a
computer.
Powered by 4-AAA batteries (included), or an optional 9V
adaptor.
Gauge Pressure:
A measure of pressure in PSI that refers to ambient
pressure.
Differential Pressure: Measurement of the difference
between two pressures.

CALIBRATION
Calibration
1. Full (HI-LOW) calibration requires a standard manometer calibrator and should be performed by a professional
calibration laboratory. Contact Sper Scientific.
2. To perform a ZERO calibration, disconnect all tubes and
do not apply pressure to the connectors.
3. Press F1 (MEAS) followed by F3 (Cali) - “Calibration” is
displayed.
3. Press F4 (ZER0) and “Cali: 0.000 PSI” will be displayed.
4. Press F4 (ENTER) again - after approximately 3 se-
conds the meter will display “OK” to indicate that the
calibration was successful.
5. If NG (No Good) is displayed, perform the calibration
again. If the meter fails to calibrate after three (3)
attempts, it should be returned to Sper Scientific.
