GENERAL INTRODUCTION
Thank you for selecting the EC3840 meter. The EC3840 is a
precision tool that measure conductivity, salinity, TDS and
temperature. A built-in microprocessor stores, calculates and
compensates for all parameters related to conductivity and
temperature determinations.
This unit has a waterproof IP67 case. The touch mode keys are
highly reliable with tactile and audio feedback. This meter uses four
“AAA” batteries. Re-calibration is not required when power is
restored.
The front of the meter 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 the user
through calibration and measurement procedures.
The model EC3840 is available with a single four-wire conductivity
cell. Other features include automatic conductivity ranging,
automatic temperature compensation, long battery life, and 50/60
Hz AC noise rejection. This unit is universal and user-friendly, for
field, industrial and laboratory applications.
INITIAL INSPECTION
Carefully unpack the unit and accessories. Inspect for damages
made in shipment. If any damage is found, notify your
Jenco
representative immediately. All packing materials should be saved
until satisfactory operation is confirmed.
WATER PROOF
Though the EC3840 meter is housed in a watertight case, DO NOT
use it underwater. The watertight case prevents permanent damage
to the unit if accidentally dropped into non-corrosive solutions.
Follow these steps immediately if the unit is immersed in any
solution:
1. 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.
