3.2 Connecting the Probe
Your meter uses a dissolved oxygen/temperature probe. The probe cable has a notched 6-pin
connector to attach the probe to the meter.
NOTE: Do not substitute other probes. For a replacement probe, see the “Accessories”
section, page 47- 48.
NOTE: Keep connector dry and clean. Do not touch connector with soiled hands.
To connect the probe:
1. Line up the notch and 6 pins on the meter’s connector with the holes in the probe’s
connector. Push down and turn the locking ring to lock into place. See Figure 4 below.
2. To remove probe, unscrew the metal locking ring by turning the ring counterclockwise
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.
