Measure Pressure (Cont.)
To perform pressure with respect to a different area,
connect a tube to the positive port, place the end of this
tube to the area to be measured and leave the negative
port open. Results will show the pressure in the target
area with respect to the area the meter is located
Use both the positive and negative ports to perform
differential measurements. Place the positive port in the
area expected to have a higher pressure, and the negative
port in the area of lower expected pressure.
3. SCALE
To select the desired units press “SCALE”. Repeated
presses of this button will scroll through PSI (pounds per
square inch), In-Wg (Inches water gauge, or water scale),
mBar (millibar), or Pa (Pascals). On the Pascal scale the
meter will automatically switch to hectopascals (hPa) when
the reading exceeds 1000 pascals. 1000 pascals is equal to
10 hectopascals.
