General Introduction; Initial Inspection; The Instrument; Battery Installation - VWR CO310 Bedienungsanleitung

GENERAL INTRODUCTION

The model CO310 is a precise instrument that measures conductivity, salinity and temperature. A
built-in microprocessor calculates and compensates for all parameters related to conductivity
and temperature determinations.
This instrument is waterproof (IP67) when the connector cap is installed. The mechanical touch
keys are highly reliable with tactile and audio feedback. This instrument uses one 9V battery. Re-
calibration is not required when power is restored.
The front of the instrument has a large LCD that displays temperature and either temperature
compensated or non-temperature compensated conductivity, salinity or TDS simultaneously
along with user prompts and mode indicators. The unit prompts users through calibration and
measurement procedures.
The model CO310 is available with a single four-electrode cell. Other features include automatic
conductivity ranging, automatic temperature compensation, long battery life, and 50/60 Hz AC
noise rejection. This meter is universal and user-friendly for field, industrial and laboratory
applications.

INITIAL INSPECTION

Carefully unpack the unit and accessories, and inspect for shipping damages. Compare
received parts with materials listed on the packing list. Notify VWR immediately of any damage
or missing parts. Save all packing materials until satisfactory operation is confirmed.

THE INSTRUMENT

Though the instrument is housed in a water-proof IP67 case, DO NOT use it underwater. The
connector is not waterproof unless the cap is installed. In case of submersion without the cap
connected, follow these steps immediately:
1. Dry the connector if necessary, and replace the conductivity probe. Rinse unit carefully with
distilled water. After rinsing and drying, inspect and clean connectors to remove all
contaminants that may affect probe connections.
2. Wait for the unit and probe to dry completely before resuming operation.
3. If the unit does not function correctly after steps 1 and 2, call VWR for possible repair or
replacement (see Warranty).

BATTERY INSTALLATION

An initial display of "BAT" on the LCD indicates approximately one hour
of battery life for unit operation within specifications. Replace battery
when "BAT" appears on the LCD. (See Figure 1.)
To replace battery, remove the two battery cover screws, battery cover
and o-ring. Replace the 9V battery. Replace battery cover and o-ring
(align the o-ring properly to insure a good seal) and fasten the two
battery cover screws for the splash-resistant feature.

Battery Disposal

This instrument is powered by a 9 volt battery, which the user must remove and dispose of when the
batteries no longer power the instrument. Disposal requirements vary by country and region, and
users are expected to understand and follow the battery disposal requirements for their specific
locale.
