1. INTRODUCTION
•The GK indicator provides an accurate, fast and versatile general
purpose indicator with parts counting, percent weighing and check-
weighing functions.
•The GK has LEDs to indicate when a weight is below the low limit,
between the limits or above the high limit next to the display. These
can work in conjunction with an audible alarm for check weighing as
well as LCD showing LO, OK and HI.
•The GK is supplied with a RS-232 bi-directional interface and real time
clock (RTC).
•The GK has a sealed keypad with colour coded membrane switches and
a large easy to read liquid crystal type display (LCD) supplied with a
backlight.
•Includes automatic zero tracking, semi-automatic & pre-set tare,
accumulation facility that allows the weight to be stored and recalled as
an accumulated total.
•OIML Approved models, GK-M, do not allow pounds units, have
calibration controlled by jumpers or passcodes and other limitations as
noted in the manual.

3. INSTALLATION
3.1. UNPACKING
This indicator must be connected to a load cell platform and calibrated as necessary
to match the platform and user requirements. See Section 15 for set-up
information.
The users application and the technical specifications of the platform or load cell will
determine the necessary configuration.
4. LOCATING
•The scales should not be placed in a location that will
reduce the accuracy.
•Avoid extremes of temperature. Do not place in direct
sunlight or near air conditioning vents.
•
Avoid unsuitable tables. The table or floor must be rigid
and not vibrate.
•
Avoid unstable power sources. Do not use near large
users of electricity such as welding equipment or large
motors.
•Do not place near vibrating machinery.
•
Avoid high humidity that might cause condensation.
Avoid direct contact with water. Do not spray or
immerse the scales in water.
•Avoid air movement such as from fans or opening doors.
Do not place near open windows or air-conditioning
vents.
•
Keep the scales clean. Do not stack material on the
scales when they are not in use.

5. CONNECTION
This indicator must be connected to a load cell platform and calibrated as necessary
to match the platform and user requirements.
The GK has a connector configured for a 6 wire load cell. Connect the load
cells/platform to the indicator as shown below. The cable length should be as short
as possible, using a large size wire to minimise errors due to resistance in the leads.
GK-M model must use the 6 wire connection and has certain limitations for wire size
and length. Refer to the Approval Test Certificate for details.
