INTRODUCTION 
 
·  The  GK  indicator  provides  an  accurate,  fast  and  versatile   general 
purpose  indicator  with  parts  counting,  percent  weig hing  and  check-
weighing functions.  
 
·  The   GK   has  LEDs  to  indicate  when  a  weight  is  below  the  lo w  limit, 
between  the  limits  or  above  the  high  limit  next  to  the  display.    These 
can  work  in  conjunction  with  an  audible  alarm  for  c heck  weighing  as 
well as LCD showing LO, OK and HI. 
 
·  The  GK  is    supplied  with  a  RS-232  bi-directional  interfac e  and  real  time 
clock (RTC). 
 
·  The  GK has a sealed keypad with colour coded membrane swit ches and 
a  large  easy  to  read  liquid  crystal  type  display  (L CD)  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.

INSTALLATION 
1.1.  UNPACKING  
This indicator must be connected to a load cell pla tform and calibrated as necessary 
to  match  the  platform  and  user  requirements.    See  S ection  15  for  set-up 
information.  
The users application and the technical specificati ons of the platform or load cell will 
determine the necessary configuration.   
LOCATING  
 
   
 
   
 
 
 
 
 
·  The  scales  should  not  be  placed  in  a  location  that  will 
reduce the accuracy.  
 
·  Avoid  extremes  of  temperature.  Do  not  place  in  dire ct 
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  l arge 
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 doo rs. 
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.

CONNECTION  
This indicator must be connected to a load cell pla tform 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.  Th e cable length should be as short 
as possible, using a large size wire to minimise er rors due to resistance in the leads.   
 
GK-M model must use the 6 wire connection and has c ertain limitations for wire size 
and length. Refer to the Approval Test Certificate  for details.
