3 PREPARING THE DIOXOR II FOR OPERATION

To prepare the instrument for operation, you must install four “C” size batteries, and (if desired) install the hose and probe as described in the following paragraphs.

For your convenience, and to ensure that the instrument will provide reliable SO2 indica- tions, the SO2 sensor is installed and the instru- ment calibrated on a known SO2 concentration at the factory.

3.1 Battery Installation

Detach the elastic strap's metal clip at the bot-
tom of the instrument, and slide off the battery
cover as shown in Figure 2. Then while observ-
ing proper battery polarity, install four “C” size
batteries into the instrument’s battery compart-
ment. (Recommended battery types: Duracell
Alkaline or equivalent). After the batteries are
installed, replace the battery cover and the	Figure 2. Battery
