GENERAL INTRODUCTION
Thank you for selecting the 6377 meter. The 6377 is a precision tool
that measures pH, mV
（
RmV
）
, Conductivity, Salinity, TDS and
temperature. A built-in microprocessor stores, calculates and
compensates for all parameters related to pH and Conductivity
determinations including pH and Conductivity electrode temperature
characteristics, electrode slope deviations, offset and buffer
solutions.
This meter has a waterproof IP54 case. The mechanical keys are
highly reliable with tactile and audio feedback. It is powered by six
AAA-size alkaline batteries or with a UL / CE approved AC adapter
(OUTPUT:DC9V). The meter also displays a “BAT” message when
the batteries are in need of replacement. Re-calibration is not
required when power is restored.
The front of the meter has a large LCD that displays pH , mV , Rmv ,
Conductivity , TDS , Salinity and temperature simultaneously along
with user prompts and mode indicators. The unit prompts the user
through calibration and measurement procedures.
An AUTOLOCK feature for both pH and mV measurements enables
the unit to automatically sense the end point and “LOCK” the display
to indicate the end point value of a measurement. AUTOLOCK and
user prompts help eliminate most errors in determining pH and mV
values,
resulting
in
precise,
repeatable
and
error-free
measurements. The 6377 can also be used in non-AUTOLOCK
mode.
The model 6377 is available with pH, ORP, Conductivity and ATC
(Automatic Temperature Compensation) probes. Other features
include up to 5 points calibration for pH and, 1 point calibration for
both Conductivity and ORP, electrode offset recognition, electrode
slope recognition, electrode efficiency display, built-in buffer
coefficients, automatic or manual temperature compensation and
50/60 Hz AC noise rejection. This meter is user-friendly for
laboratory application.
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.
