Connecting the Base Temperature Probe, Temperature and Humidity
Probe or Thermoanemometer Probe to the Micromanometer
These probes have a “D” shape overmolding on the mini-DIN connector which must align with the
connector on the right hand side of the micromanometer (see Figure 13). This will ensure the probe is
properly connected and remains so during use. Once connected and turned on, refer to the
DISPLAY
SETUP
for displaying the desired measurements.

Using the Telescoping Thermoanemometer Probes or Temperature
and Humidity Probe
The telescoping thermoanemometer 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.
The telescopic temperature and humidity probe contains the temperature and humidity sensors. This probe
is ideally suited for in-duct measurements and provides calculations for wet bulb or dewpoint
temperature.
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 probe from extending.
