INTRODUCTION
This versatile hand-held instrument provides highly accurate relative humidity measurements and temperature with calculated dew point in Celsius or Fahrenheit.
This instrument covers the extended measuring range of 0 to 100% RH, –40 to +140°F (–40 to +60°C) temperature, and –130 to +140°F (–90 to +60°C) for dew point.
The instrument is designed for easy operation and includes the following features:
Operator selection of temperature scale
Resolution of 0.1 (% RH, °F, °C, and DP)
LCD with three four-digit displays
Six-pin circular DIN connector input for
probe
Hold feature for temporarily retaining a
reading
Two-point field calibration capability for
humidity or temperature

BATTERY INSTALLATION AND
REPLACEMENT
WEAK BATTERIES
CAUTION
INSTRUMENT. DEAD BATTERIES CAN LEAK AND CAUSE DAMAGE TO UNIT.
When battery indicator illuminates, battery life is approximately 8 to 10 hours. The battery indicator starts flashing when battery life is less than one hour. At that point, the battery
must be changed. If the battery charge gets too low, the display blanks.
See SPECIFICATIONS for correct battery type.
1) Before changing battery, turn instrument off and disconnect probe.
2) Loosen screw and lift battery cover off back of case.
3) Remove the two AA batteries.
4) Observe polarity, and insert two new batteries.
5) Install cover and tighten screw.

AC ADAPTER
An optional AC adapter can be used for power to conserve batteries. The adapter is not a charger and will not charge batteries. The adapter connects to the bottom of the instrument. When the adapter is connected, the batteries are disconnected.
Refer to ACCESSORIES for adapter information.
CONNECTING THE PROBE
A five-pin socket is located at the top of the instrument. Align the slot locator in the plug of the probe with the slot in the socket as shown below. Insert the plug fully into the socket and turn the locking ring clockwise to secure the attachment.
