Press and hold ENABLE then press ON or OFF as appropriate.
Auto Zero:
The cycle will begin as soon as the instrument is switched on. This is factory set at a 30
second interval upon switch on and thereafter at 60 second intervals.
To change this timing see User Menu page 05.
The instrument contains a miniature solenoid valve, which isolates the pressure sensors
during auto zero. The valve emits two clearly audible clicks, which signal the start and end of
the auto zero process.
Battery Low:
The battery condition is monitored every time the instrument auto zeroes.
When the 'battery low' warning appears, the battery must be replaced immediately,
otherwise the readings obtained will be unreliable.
If at any time the readings seem suspect, check the condition of the battery by zeroing the
instrument manually using ZERO.
If in doubt replace the battery. For rechargeable instruments charge the internal battery
with the charger supplied.
Units:
The unit of measurement is shown on the right hand side of the display.
Being an auto ranging instrument, the correct resolution and the decimal point will be
displayed according to the pressure being applied.
FAST SLOW:
Some pressurised circuits exhibit pressure and velocity fluctuations, which can be
disconcerting; if unacceptable fluctuations occur, press FAST SLOW and verify that the slow
indication is displayed on the screen.
Store:
Shows the number of readings stored on the instrument.
To store data manually press STORE while the instrument is in Slow1, Slow2, Slow3 or Slow4
mode: the reading on the display will be logged and the counter will increase by one.
During data logging the counter will increase by one every time the instrument records a
value. For information on data logging see Option Menu pages 08 and 09.
Audible Feedback:
While the instrument is on, audible feedback can be heard every time a key is pressed.
Signal In / Reference:
Pressure ports. The instrument responds to positive, negative and differential pressure.
RS 232 Port:
Is located between the two ports.
