3.2 Connecting the Probe

The DO 100 uses a special notched 6-pin connector to attach the probe to the meter.

NOTE: Do not substitute other probes or electrodes. For replacement probe, see

the Section 14 “Accessories” on page 52.

NOTE: Keep connector dry and clean. Do not touch connector with soiled hands.

To connect the Dissolved Oxygen probe:

1. Line up the notch and 6 pins on the meter with the holes in the 6 pin connector. Push

down and screw the metal sleeve to lock the probe connector into place. See Figure 4.

2. To remove probe, unscrew the metal sleeve and slide up the probe connector. While

holding onto metal sleeve, pull probe away from the meter.

CAUTION: Do not pull on the probe cord or the probe wires might disconnect.
