Readings and Measurements
These operations must be carried out in compliance with the methods described in this manual.
Remember, measurements taken with batteries in need of recharge can give false measurements.
Checking pressure
The pressure gauge has two measuring inputs, one for the pressure (positive) and one for the depression
(negative).
To measure the positive pressure, apply the supplied tube on the input on the left making sure to let
opened the entrance to the depression.
To measure the negative pressure (depression), apply the tube on the input on the right making sure to
let opened the input pressure.
To measure the difference of two pressures, apply the higher pressure on the positive input and the other
on the negative input.
After the reading, appear on the display the pressure difference that the instrument will measure between an
input and the other.
1) Turn on the instrument as above
2) Insert the tube in the “Press” input
3) Use the tube to connect the instrument to the pressure or depression source, for measurement; the
instrument measures both positive and negative pressure.
PRESSURE GAUGE Function.
Press the
button and then the “Press” function button.
PRESSURE GAUGE Function.
Press the “Press” button to access the Pressure Gauge function with its mmH

O scale;;
When the instrument is switched on it positions itself on the 999 mmH

O scale
If the pressure measured is higher, the instrument automatically positions itself on the higher scale of
999 mmH

O.
If you want to use the mbar scale, press the “Press” button again.
The instrument positions itself on the 30.9 mbar scale.
If the pressure measured is higher, the instrument automatically positions itself on the higher scale of
150 mbar
SWITCH OFF. Press the OFF button for 5 seconds.
