1. Description
• This meter is a complete digital psychrometer and a very valuable HVAC diagnostic
tool. As a psychrometer, it measures wet bulb(WB), dry bulb(DB), percent relative
humidity(RH%), and dew point(DP).
As a diagnose problems with air flow across the evaporator. It can also calculate the
target superheat of a fixed restrictor air conditioning system.
• Use the NORM mode (Normal psychrometer) to display wet bulb (WB), dry bulb(DB),
percent relative humidity(RH%),or dew point(DP).
• Use TSH (Target Superheat) to help set the proper refrigerant charge for a fixed
restrictor system. Use the thermouple to easily measure Actual Superheat without the
need of additional charts.
•Use TEET (Target Evaporator Exit Temperature) to ensure proper evaporator airflow.
2. How it Works
• This meter has three sensors. One for RH% and two for temperature.
Depending on where you place these sensors and how you set up the meter. The meter
will display the measurements and the results of calculations from these inputs.
• Inside the "cage" on the top of the meter is a thermistor, right next to the RH% sensor.
It's used to measure ambient air(DB). In addition to the thermistor, a thermocouple can be
plugged into the temperatures (including wet bulb) in hard to reach places. such as in front
or in back of the evaporator coil.
• To use this meter, you must tell it what test you want it to perform.
Select the parameter you want to measure, and choose which temperature sensor to use,
either the thermocouple (T/C) or the "caged" thermistor (NTC). Take your measurements.
Read the results, both the directly measured readings and the calculated results.
