3. INSTRUCTIONS
3-A. General Instructions
The Manometer measures “Gauge Pressure.” This combines Differential
pressure with a PSI measurement as referenced to ambient pressure. When
the manometer is first powered on, the entire LCD display flashes for
approximately 3 seconds. The LCD is divided into two distinct sections: One
large (Primary) top screen and one smaller section at the bottom-right of the
LCD (Relative Clock). The pressure measurements are constantly updated in
the 2 display areas. Check that the tubing is not leaking or damaged before
use. The start-up mode is programmable. The display will default to the mode
last used and the meter defaults to the setting used during the last operation.
•
Turn the unit on with the
ON/OFF
button.
•
Press the
REC
button once, and the relative clock starts in the lower right
screen. "REC" is displayed in the middle-left of the LCD (Pg 6, Fig B). The
DIF
button will not operate at this time.
•
Press the
REC
button repeatedly to cycle through MAX (Pg 6, Fig C) and
MIN (Pg 6, Fig D) and back to the current pressure. To exit the record
mode, press and hold the
REC
button for 3 seconds.
