Measuring

The thermo-hygrometer will automatically make measurements on enabled channels at the set
period when a sensor is attached. Channels are enabled using the CHANNEL SETTING func-
tion in the CHANNEL menu. The measurement period is also set with this function.
Unit of Temperature
The thermo-hygrometer is capable of displaying temperature in Celsius (C) or Fahrenheit
(F). The unit of temperature applies to temperature measurements on either channel that are
displayed, recorded, or printed. Recorded data is viewed or printed with the currently set unit
of temperature. The unit of temperature is set using the DISPLAY SETTING function in the
DISPLAY menu or the SYSTEM SETTING function in the SYSTEM menu.
Recording Measurements
The thermo-hygrometer will automatically record measurements on enabled channels at the set
period. Recording is enabled using the RECORD SETTING function in the DATA RECORD
sub-menu in the DATA menu. The record period is also set with this function.

Sensors

The standard-accuracy sensor and high-accuracy sensor are used to measure temperature and
relative humidity. The sensors attach to the thermo-hygrometer by plugging into the top or side
panel of the instrument.
The sensor contains a memory device that stores information about the sensor and automati-
cally transfers this data to the thermo-hygrometer when the sensor is attached. This ensures that
the settings used to measure and calculate temperature and humidity always match the sensor
being used.
CAUTION: Sensors are fragile devices that can be easily damaged by mechanical shock,
overheating, and exposure to fluids or dust. Damage may not be visibly apparent but
nevertheless can cause drift, instability, and loss of accuracy. Observe the following
precautions:
DO NOT allow sensors to be dropped, struck, or stressed.
●
DO NOT overheat sensors beyond their recommended temperature range.
●
DO NOT expose sensors to harmful vapors, fumes, dust, or condensation.
●
DO NOT allow sensors to come into direct contact with any fluids.
●
Sensor Accuracy
To achieve full accuracy with the thermo-hygrometer sensors, a few precautions should be
noted.
