Setup for Waterless Wetbulb measurement (airflow rate)

Index: none, ACGIH, Navy, Marine, EPRI and select either: WBGTi (indoor), WBGTo (outdoor) for Index setting.

Index Setting Notes

TLV and action limit only apply to the ACGIH Index. EPRI Navy, and Marine will ignore this setting.

Clothing Correction parameters are set from 0 - 9.9°C. This is a clothing correction for the WBGT in degrees Celsius and is applied to the selected WBGT when the work duration is calculated. (It will not affect the WBGT as displayed by the unit.) This value should typically be set to 0.0 for the Navy. (The field is noted as “Clo Corr”.)

3.Press the I/O Enter key to change a parameter. Time and date require using the Up/Down Arrows and I/O Enter keys to modify each number.

NOTE: at any time, you can move back one level, by pressing the Run/ Stop key.

4.Exit Setup by pressing the Run/Stop key.

Setup for Waterless Wetbulb measurement (airflow rate)

For the Waterless Wetbulb sensor calculation, an airflow rate (or wind speed) of 0.3 m/s is recommended and is the default setting of the instrument. NOTE: only QTº46 supports the optional air-probe accessory.

If an air probe is not selected, the average wind speed of the environment should be configured. This value is then entered into the Flow screen under the setup menu.
