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
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).
2.
SENSORS AND GUARD 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!
1.
Remove calibration cup: firmly hold the
calibration cup with one hand and twist the
cup’s retaining nut counterclockwise until it
loosens (no need to keep turning; once it is
loose you can remove it). Remove the cup
and set aside in a clean, dry place.
2.
Firmly hold the bulkhead with one hand and
turn the sensor guard counter-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; clean any debris on the sensor tips
with a lint-free cloth and rinse with water
.
Carefully “test” the connection of each sensor
by grasping the sensor near the bulkhead
between your thumb and finger, and try to
turn the sensor to determine if it is loose. If
the sensor moves or twists
at all
(sensors
should
firmly
be in place), reconnect the
sensor guard and inform the team leader.
(See “Settings and Troubleshooting” section
under “Sensor Installation”.) If sensors are
firmly in place, proceed to next step.
4.
Carefully slide the sensor guard over the
sensors and push it toward the bulkhead until
the sensor guard threads align with the
bulkhead threads. Carefully finger-tighten
the sensor guard clockwise.
NOTE:
If any resistance is felt, loosen the
sensor guard completely to prevent cross-
threading. Incorrect installation may cause
damage to the sensor guard or bulkhead.
