balance, etc. and will guide you through the variou s applications. Please
read this Manual thoroughly before starting the ope ration. If you need any
clarifications, feel free to contact your supplier or Adam Equipment.
PRODUCT OVERVIEW
The PGW..M balances are ideal for laboratory and ge neral purpose weighing.
The balances can also be used for some advanced wei ghing functions. The
balances are configured at the factory for complian ce with EN 45501, OIML
R-76.
PGW..M series
FEATURES:
· Large easy to read LCD display with backlight
· Standard applications include weighing, check
weighing, percentage weighing, parts
counting, animal / dynamic weighing, net / total
and density determination
· Automatic and semi-automatic span adjustment is do ne with internal
calibration mass only. It is operational after 5 mi nutes of switching the
balance on, when the temperature changes by 2ºC and on every 4 hrs
after switching on. This function can not be disabl ed by user.
· The weight values on the display and the RS-232 ou tput are marked with
brackets on the least significant digit.
· Can be configured to print a GLP Compliant report after each calibration to
include the time, date, balance number and a verifi cation of the calibration
· Automatic temperature compensation
· Display in 4 languages- English, French, German and Spanish
· Capacity tracker
· Date and time
· Easy to use, sealed keypad

4 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 SETTING UP THE BALANCE
5.1 ASSEMBLING THE BALANCE
· Locate the balance on a solid surface, free from v ibration
· 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 fi tted) and then the
stainless steel pan on the weighing platform
· Place the draught shield frame and the top cover a round the pan (for
mg models only)
· Level the balance using the adjustable feet and sp irit level
· Connect power to the balance
· For best performance, let the balance warm up for 30-60 minutes and
calibrate before using
5.2 LEVELLING THE BALANCE
After placing the balance in a suitable place,
level it by using the spirit level on the rear of t
he
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

Label

The display will show zeroes accompanied by the 0 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 “0 “ symbol is on to the left of the display area. 6 DISPLAY This display includes areas for the weight value (u p to 7 digits), symbols for common weighing units, tare, s tability, zero, arrows used for check weighing, a 0-100% bar graph and a text area for menu. The LCD has 7 x 7-segment digits for the weight and 10 x 14- segment digits for messages, symbols for weighing u nits and common use such as stability etc. The 14 segment digits allow a large amount of flexi bility for any unusual weighing unit, and messages concerning operation or errors.

The Percentage indicator known as capacity tracker has 10
large segments for showing the percentage of the to tal range
used. This is also used during check-weighing.
The 10 digit text area is used to display the curre nt weighing
mode or to guide the user through processes such as density
determination.
SYMBOLS AND TEXT
