D.
External temperature sensor (T1)
The thermocouple is located at the bottom right side of the monitor. It can be used with any
optional or separate Type K thermocouple probe and/or wire. The T1 temperature
measurements are displayed on the Large Font
MEASURE
screen only as T1.
E.
Differential Pressure / Air Velocity sensor.
If the monitor comes with the Differential Pressure option and/or the air velocity option
(optional separate L-type Pitot tube and pressure tubing), the internal pressure sensor is a
very low range pressure sensor. The Velocity measurements are displayed on the
MEASURE
screen only as
VEL
. Differential Pressure is displayed on the
MEASURE
screen only as
∆P
.
F.
Connecting Differential Pressure Hoses:
Connect Metal Hose Connections to either P+ or P- Connection as shown. P+ only will
give you Positive pressure; P- only will give you Negative pressure. Plug in both as shown
below for Differential Pressure.
All single & differential readings are shown on main MEASURE
screen as ∆P.
