Operation

Power

PressthePower buttontoswitchthemeterONorOFF.IfthemeterdoesnotswitchON

whenprompted,checkthatafresh9Vbatteryisinstalledintherearbatterycompartment.To

conserveenergy,themeterswitchesOFFautomaticallyafter30minutesofinactivity.

RelativeHumidityandTemperatureMeasurements

1. SwitchthemeterON.

2. Holdtheprobeintheareatobetested&allowadequatetimeforreadingstostabilize.

3. ReadtheRelativeHumiditymeasurementin%RHunitsatthecenteroftheLCD.

4. ReadtheAirTemperatureindegreesCorFonthelowerdisplaydigits.

NOTE:Donotimmersetheprobeinliquid;itisintendedforuseinaironly.

oF/oCunitsselection

1. EnsurethatthemeterisswitchedOFF.

2. Openthebatterycompartmentbycarefullyslidingtherearcompartmentcoverdownward.

3. Removethebatteryfromthecompartment.Thebatterycanremainconnectedtothe

red/blackwiresbutitmustbephysicallyremovedfromthecompartmentcavity.

4. Theunitofmeasurecanbechangedusingthe surface mount selector switch located on the

printed circuit board accessible through an opening in the battery compartment. See the

Description section of this manual for the location of the opening.

5. With good lighting, locate the switch visually. Then use a non-conductive screwdriver or other

tool to toggle the switch left or right. The switch is labeled in the battery compartment. If the

label is removed, move the switch to the left for degrees F and to the right for degrees C.

6. Place the battery back in the compartment as detailed in the battery replacement section.

7. Switch the meter ON and verify that the LCD display shows the desired unit of measure.

MAX‐MINRecording

1. PresstheMAX‐MINbuttontodisplaythehighestreadings(maximum)recorded.The

readingsshownwillbethehighestreadingsmeasuredsincethemeterwasswitchedON.The

MAXiconwillappearatthetopoftheLCD.

2. PresstheMAX‐MINbuttonagaintodisplaythelowestreadings(maximum)recorded.The
