INSTALLING BATTERIES INTO THE 6920DW
To install the 8 AA-size alkaline batteries into the sonde, refer to
the following directions and the adjacent figures.
Position the bail so that it is perpendicular to the sonde and use it as
a lever to unscrew the battery cap by hand. Then slide the battery lid
up and over the bulkhead connector.
Insert batteries, paying special attention to polarity. Labeling on the
top of the sonde body describes the orientation.
F
Check the O-rings and sealing surfaces for any contaminants that could interfere with the seal of the battery
chamber.
Lightly lubricate the o-rings on the bottom of the threads and on the
connector stem as shown in the figure at the right.
Return the battery lid and tighten by hand.
DO NOT OVER-
TIGHTEN.
2.3.4 STEP 4 - CONNECTING A FIELD CABLE
As shown in the picture at left, the 6920DW and
600DW-B have a sonde-mounted cable connector
for attachment of cables. Two types of cables are
available – a “field cable” in various lengths up to
200 feet and a short 6067B laboratory calibration
cable.
To attach a field cable to the sonde connector,
remove the waterproof cap from the sonde
connector and set it aside for later reassembly
during deployment or storage. Then connect your
field cable to the sonde connector.
A built-in “key” will ensure proper pin alignment.
Rotate the cable gently until the “key” engages and
then tighten the connectors together by rotating
clockwise. Attach the strain relief connector to the
sonde bail. Rotate the strain relief connector nut to
close the connector's opening.
