activated and automatically zeroed (if it does not
read 0.00 proceed as follows

2. Momentarily Press the     key and the display

should zero /- 0.01 if not repeat until it
does

3. Connect pressure meter to installation or

equipment to be tested using appropriate hose
connection in accordance with the manufacturers
instructions

4. The pressure reading will appear on the display.

To activate the backlight in poor light conditions
press the     key at any time

5. If the reading is erratic or changing activate the

smoothing function by pressing the '=' key

6. To convert the displayed pressure reading to

another engineering unit depress the 'UNIT' key
anytime and scroll through to the desired units of
pressure.
