Measurements - Temperature & Pressure (continued)
Measuring Pressure -
1. Ensure you have Pressure Sampling Tube connected to one or both of the
Pressure Ports and there are no restrictions in the tubing (see figure below). The
716 is supplied with a pair of pressure adaptors to allow 1/4” bore hose to be
attached to the pressure ports.
2. Zero the display by pressing the “Zero” Key (left blue soft key).
3. Connect the tube(s) to the device under test and read the pressure on the
display.
The 716 incorporates a differential manometer. Pressure applied to the (-) port is
subtracted from the pressure applied to the (+) port.
