3.0  UNPACKING THE BALANCE 
 
Remove the balance from the packing by carefully lifting it out of the box.   
Inside the box you will find everything needed to start using the balance- 
 
 
 
9 AC adapter 
9 Four rubber pan supports  
9 Stainless Steel Top Pan 
9 Draught shield (for mg models only) 
9 This User Manual  
 
4.0  LOCATING THE BALANCE 
  
  
   
   
   
  
• The balance 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 balances in 
water. 
 
• Avoid air movement such as from fans or 
opening doors. Do not place near open 
windows or air-conditioning vents. 
 
• Keep the balance clean. Do not stack material 
on the balances when they are not in use.

5.0  SETTING UP THE BALANCE 
Screws 
with nuts5.1 ASSEMBLING THE BALANCE 
 
• Locate the balance on a solid surface, free from vibration 
 
• For PGWi models, tilt the balance 
on it’s side and remove the two 
shipping screws and nuts before 
use. If you need to ship the 
balance, replace the screws but do 
not over-tighten which may damage 
the internal mechanisms 
 
 
• Gently place the 4 pan supports (if not already fitted) and then the 
stainless steel pan on the weighing platform 
 
• Place the draught shield frame and the top cover around the pan (for 
mg models only) 
 
• Level the balance using the adjustable feet and spirit level 
 
• Connect power to the balance 
 
• For best performance, let the balance warm up for 30-60 minutes and 
calibrate before using 
 
Label 
 
5.2 LEVELLING THE BALANCE 
 
 
 
After placing the balance in a suitable place, 
level it by using the spirit level on the rear of the 
balance. To level the balance turn the two 
adjustable feet at the rear of the balance until 
the bubble in the spirit level is centred.  
5.3 WARM-UP TIME 
 
 
 
 
 
Attach the power supply cable to the connector 
on the rear of the balance. Plug the power 
supply module into the mains.  The display will 
indicate the balance serial number (if set) and 
the software revision number followed by the 
capacity of the balance. Next the balance will 
run a self-test by displaying all segments

followed by a symbol indicating the balance is in 
busy mode. If the balance serial number is not 
set the display will show dashes. The display 
will show zeroes accompanied by the Î0Í 
symbol. If the balance is not used for a long 
time, it will go back to the auto-calibration mode.
Before you start weighing, you have to wait for the balance to achieve a 
stable internal temperature.  Typical initial warm-up time suggested for a 
balance already at room temperature is about 1 hour.  
 
 
 
A stable sign ~ is shown when the balance is in 
stable condition.  It will turn off if the balance is 
not stable. 
Exact zero is shown when the “Î0Í “ symbol is 
on to the left of the display area. 
6.0  DISPLAY 
 
 
The LCD has several areas- 
 
- A large 7 digit area to display the weight with symbols for 
common weighing units on its right and symbols for zero, tare 
(Net) and stability on the left. 
 
- A 10 digit area which allows a large amount of flexibility for 
displaying text messages concerning menus, operation and 
errors, for example to display the current weighing mode or to 
guide the user through processes such as density 
determination 
 
- A percentage indicator known as capacity tracker which is a 
0-100% bar graph consisting 10 large segments for indicating 
the percentage of the total balance capacity used and arrows 
for check weighing.
