2. OPERATION

Please read all instructions before operating the WP4C to ensure it performs to its full
potential.
PRECAUTIONS
METER instruments are built to the highest standards, but misuse, improper protection,
or improper installation may damage the sensor and possibly void the manufacturer's
warranty. Before setting up the WP4C, follow the recommended installation instructions
and arrange proper protections to safeguard the instrument from damage.

2.1 INSTALLATION

Follow the steps listed in

Table 1 Installation
Portable 12-V power inverter (field installation)
Select Clean, Level Location
Select a location where the temperature remains fairly stable to avoid
temperature changes that can affect accuracy (away from air conditioner and
heater vents, open windows, etc.). If in the field, a Styrofoam box, for example,
can help minimize temperature effects.
Observe clean practices to prevent contamination of the sample chamber.
Maintain a level surface to reduce the chance of spilling sample material and
contaminating the sample chamber.
Remove Sample Cup
Pull open the sample drawer by turning the knob to the OPEN/LOAD position.
Remove the empty upside-down disposable sample cup (used to protect the
drawer during shipment) and set aside.
Plug In Instrument
Plug the power cord into the back of the WP4C unit and an outlet. Use only the
supplied power cord.
If in the field, plug the instrument into a 12-V portable power inverter that plugs
into the 12 V output of a vehicle.The inverter should have a continuous output of
at least 140 W.
NOTE: When the instrument is on, it draws up to 1 A. Check the battery rating to determine
how long it will power the instrument (for example, if the battery is rated for 60 Ah, it will
work for 60 h when the vehicle is not running).
WARNING: An incorrect main power voltage can damage the instrument.
Turn the Unit ON.
The ON/OFF switch is located on the lower right corner of the WP4C back panel.
Allow the WP4C a 15- to 30-min warm-up period to ensure accurate readings.
Check the calibration of the instrument (Section 4.1).
