SPECIFICATIONS

Embedded microcontroller Custom one-chip LSI device

Display type Liquid-crystal with green backlight

Display size 2.05 x 1.5 in. (52 x 38mm)

Parameters measured Temperature, relative humidity (R.H.), dew point,

wet-bulb temperature

Measurement range For temperature, 32º to 122ºF (0º to 50ºC); for R.H., 5 to 95%;

Operating relative humidity 0 to 85%

Power source 6 Alkaline “AA” batteries or optional 9-VDC AC adapter

Power consumption 3.5 mADC (normal operation, with backlight off and SD card

not saving data); 28 mADC with backlight on and card saving

data; 40 mADC with backlight on and card saving data

Dimensions of meter 6.97 x 2.68 x 1.77 in. (177 x 68 x 45mm)

Weight of meter 1.08 lb. (489g)

MAINTENANCE & TROUBLESHOOTING TIPS

When the icon appears in the left corner of the display, it’s time to replace the six

“AA” batteries that power the instrument (although measurements will remain valid for

several hours after the low-battery indicator first appears). Replacing the batteries requires

removing the two screws that hold the battery compartment cover in place, as explained in

Step 1 of the setup procedure. After inserting fresh batteries in the correct orientation,

tighten the screws to secure the cover.
