YSI ProDSS supplement 1 July 2015
MULTIMETER: YSI-ProDSS
EQUIPMENT NEEDED
• YSI-ProDSS multimeter
• data sheet, clipboard, pencil
Note:
The ambient temperature range
over which the battery pack can be
discharged is -20°C to 60°C (-4°F to
140°F). Use of the battery pack outside of
this temperature range may damage the
performance of the battery pack or may
reduce its life expectancy.
INITIAL INSTRUMENT PREPARATION:
1.
CABLE CONNECTION
Inspect the cable connection between the
handheld meter and the cable.
If cable is not connected to the meter,
make
sure the connectors are clean and dry
before connecting!
If connecters are clean
and dry, align the keys on the cable assembly
connector with the slots on the instrument
connector. Push together firmly, and then twist
the outer ring clockwise until it locks into place.
The metal pin should “snap” into place and be
visible through small hole in the outer ring (see
image below).

2.
SENSOR GUARD AND
SENSOR(S) CHECK
If any of the individual sensors are not
connected, Refer to “Settings and
Troubleshooting” section for sensor installation.
If there is an empty “slot” with no sensor
installed,
a port plug or sensor must be
installed or the bulkhead will be
damaged!
Remove calibration cup and inspect the sensor
guard and sensors.
1. Firmly hold calibration cup with one hand
and twist the cups retaining nut
counterclockwise until it loosens (you do not
need to keep turning, once it is lose you can
remove it). Set the cup aside in a clean and
dry place.
2. Firmly hold the bulkhead with one hand and
turn the sensor guard clockwise until
completely unthreaded. Set aside the
sensor guard in a clean dry place. Use
caution once the sensors are exposed!
3. Conduct a quick visual inspection of the
sensors; look for any debris on the sensor
tips, if there is carefully clean with a lint-free
cloth and rinse with water
.
Carefully “test”
the connection of each sensor by grasping
the upper portion of the sensor between
