Using Optional Telescoping Thermoanemometer Probes
The telescoping probe contains the velocity, temperature, and humidity
sensors. When using the probe, make sure the sensor window is fully
exposed and the orientation dimple is facing upstream.
NOTE: For temperature and humidity measurements, make sure that at
least 3 inches (7.5 cm) of the probe is in the flow to allow the temperature
and humidity sensors to be in the air stream.
Extending the Probe
To extend the probe, hold the handle in one hand while pulling on the
probe tip with the other hand. Do
not hold the cable while extending the
probe as this prevents the robe from extending.
Retracting the Probe
To retract the probe, hold the handle in one hand while gently pulling
the probe cable until the smallest antenna section is retracted.
Do not use the instrument or probes near hazardous
voltage sources since serious injury could result.
Thermocouple Ports
The 7575 series includes two thermocouple ports at the base of the monitor.
Any K-Alloy thermocouple with mini-connector can be attached. See
Display Setup for setting the thermocouple temperature readings to be
displayed as TC1, TC2, or TC1-TC2.
Connecting the Thermocouples
The K-Alloy thermocouple with mini-connector has one terminal wider
than the other. The wider terminal will be inserted into the bottom of the
TC1 or TC2 connector port.
