Humidity Recording

As the gauge operates, it records the maximum and minimum temperatures and humidities reached since the last time the Clear Button was pressed. Use a small, pointed instrument, or an unbent paper clip, to press the Max /Min Button (Figure 12) on the gauge. Press once to read the maximum, and once again to read the minimum. Press the button a third time to return to the current reading. The gauge shows MAX or MIN when either of these values is displayed.

Press the Clear Button (Figure 12) to delete the previous maximum and minimum readings and begin recording anew.

A slide switch on the side of the gauge (Figure 13) allows you to select between °Centigrade and °Fahrenheit temperature readings. Slide the switch UP to select °Centigrade; and DOWN to select ° Fahrenheit.

Replacing the Gauge Battery

The gauge is powered by a 3.0 volt, lithium, Type CR2032 battery which you can obtain locally.

The battery is contained in a built-in slide in the top of the gauge (Figure 14). Just pull the battery slide up with your finger to open, and remove the battery. When replacing the battery, notice that the battery is marked with a “+” sign on one side, and the battery slide is marked with two “+” signs (Figure 15).All “+” signs must be on the same side and must face the front of the gauge. With the battery in the slide, press the slide downward until it clicks into place.
