Page 8 of 44

5.0 SETTING UP THE BALANCE

5.1 ASSEMBLING THE BALANCE

• Locate the balance on a solid surface, free from vibration

• 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

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.

Page 9 of 44

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.

6.0 DISPLAY

This display includes areas for the weight value (up to 7 digits), symbols for common weighing units, tare, stability, zero and low battery, 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 14segment digits for messages, symbols for weighing units and common use such as stability etc.

The 14 segment digits allow a large amount of flexibility 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 total range used. This is also used during check-weighing.

The 10 digit text area is used to display the current weighing mode or to guide the user through processes such as density determination.

Exact zero is shown when the on to the left of the display area.

9.0 OPERATIONS

9.1 INITIALISATION

When the balance is first switched on, it will display the balance serial number (if set), software revision, model capacity and then all segments on the display will be shown. Overall the time taken is usually 5 -10 seconds.

If a passcode has been set, the display will show “PASSCODE” and the main display will show a zero. In this case you must enter the passcode to continue using the numeric entry method (see section 7.1). A different passcode may be set for a Supervisor to weigh or to have access to the selected User menus. If the passcode has not been set the balance will continue as below.

The display will show zero reading along with the zero symbol “

Î0Í” and the

weighing unit last used. If automatic time calibration is enabled the balance will calibrate after power up and again after the pre-set time interval.

9.2 PASSCODES

If a passcode has been set to limit access to the weighing functions of the balance the display will show “PASSCODES” with the main digit set to zero. The display will change to show 7 digits set to zero with the rightmost digit flashing. Use the numeric entry method (see section 7.1) to enter the code. Make sure to enter the correct passcode to continue. See the Section 13.6 for details.

Pressing the [Cal] key will start calibration. Calibration can also be initiated by a change in internal temperature or a set time period as determined by the user (see section 13.5).

10.1.1 Calibration using Internal Calibration mass

• Pressing [Esc] will abort the calibration at any time

• Check the display is at zero. Tare if necessary

• Calibration will begin automatically. When calibration is complete the

balance will return to weighing.

10.1.2 Calibration using External Calibration mass

• Pressing [Esc] will abort the calibration at any time

• Check the display is at zero. Tare if necessary

• Press the [Cal] key

• The display will show the balance setting a new Zero condition by

showing “LOAD 0”. Make sure the pan is empty then press the [Enter] key to continue

• The balance will then show the value of the calibration mass required sounding a beep, for example “LOAD 1000 g”

• Place the mass on the balance. Press [Enter] to continue

• The display will show the busy symbol and after calibration is complete

it will display “UNLOAD” sounding a beep. Remove the weight. Another beep will be heard confirming the unloading action. The balance will then return to normal weighing.

Page 25 of 44

10.2 AUTOMATIC CALIBRATION

The balance will have the ability to calibrate (or ask for calibration) when the balance has automatic calibration enabled and the conditions of the automatic calibration have been meet.

Conditions that will cause an automatic calibration are:

1. Internal temperature change greater than a preset amount, typically 2ºC

2. Time since last calibration exceeds a preset time, typically 4 hours or 15 minutes after power is applied.

On the balances with internal calibration the calibration will be done automatically when the balance is at a stable zero. . The user knows a calibration is asked for by the flashing of the “CAL” symbol on the display. The display will show a 5 second countdown when calibration will start. If the user presses the [Esc] key the calibration will be delayed one minute to allow time for a process to be finished.

On balances with external calibration the balance will call for calibration to be carried out by flashing the “CAL” symbol on the display. As soon as the balance is calibrated the symbol will be turned off.

The Auto calibration feature can be enabled, disabled or changed within the user options to meet the requirements of the users.

10.3 CALIBRATION ERRORS

Occasionally during calibration an error will be detected. These errors can be caused by:

Unstable readings Improper calibration weights being used Large shifts of zero from the factory settings

When an error is found a displayed message will be shown and the calibration must be done again. If the balance has error messages more than once it is possible the mechanics have been damaged.

Page 26 of 44

11.0 RS-232 INTERFACE

The balances have the ability to send or receive data over the serial interface. The weighing data can be sent over the interface either automatically or when

the user presses the [Print] key. The user has control over what data is to be printed. The following gives a description of the RS-232 interface.

HARDWARE

The RS-232 interface is a simple 3 wire connection. The input and output connections are:

Connector: 9 pin D-sub miniature socket Pin 2 input to balance RXD Pin 3 output from balance TXD Pin 5 Signal ground GND

Handshaking is not applied.

Baud rate: 4800, 9600, 19200, 38400 Parity: NONE (=8N1), EVEN (=7E1) or ODD (=7 O 1) All lines are terminated with carriage return and line feed (<CR><LF>). In continuous output mode, or if single-line output on demand is selected, the

serial output format will be a single line in the form “1234.567 g<CR><LF>”. The format of the single-line output will change depending on the mode in

which the balance is operating, as described below. If output on demand is selected, the user may optionally configure the serial

output as a choice of 3 styles of form, either in a default format or in one of two custom formats. Each of the custom formats can be configured to output up to 15 lines of data. The data types that can be printed are:

NAME TEXT PRINTED

ID number ID no.: xxxxxxxxxxxx Serial number Serial no. xxxxxxxxxxxx Date DATE dd/mm/yyyy Time TIME hh:mm:ss Net weight Net: xxx.xxx g Gross weight Gross: xxx.xxx g

Page 27 of 44

Tare weight Tare: xxx.xxx g Unit weight Unit wt: xxx.xxx g Count Count: xxxx pcs Reference weight Ref. wt: xxx.xxx g Percent Percent: xx.xxx % Checkweigh lower limit Low: xxx.xxx g Checkweigh upper limit High: xxx.xxx g A blank line printed <CR><LF> only.

Any of these can be printed on any of the 15 lines available. Not all items need to be used and any one can be used more than once (see section 13.3).

The data for each form will be preceded by a start-of-header <SOH> character (01) and terminated with an end-of-transmission <EOT> character (04). These characters will be ignored by a serial printer but will allow a computer program which reads the data to distinguish between this block report format and the single-line output format described above.

STANDARD FORMAT

The balance will print the following data as the standard form. The standard form cannot be changed. The format of the custom forms #1 and #2 will be the same as the standard form until modified by the user.

Line 1 Date Line 2 Time Line 3 Blank line Line 4 ID number Line 5 Blank line Line 6 Result Line 7 Blank line Line 8 Blank line

This will result in a printout that looks like:

Date: 23/09/04 Time: 15:45

ID No: 123456

Net: 123.456 g

*NOTE:

The format of the results line will change depending on the mode in

which the balance is operating, e.g. Normal weighing, Check weighing, Animal weighing: “123.456 g” Parts counting: “1234 pcs” Percent weighing: “12.345 %”

Page 28 of 44

new passcode if desired. A passcode set to zero will disable the security feature and allow unlimited access.

13.6.1 Forgotten Passcodes

Keep a record of the passcode to ensure you can access this section again. If however you have forgotten your passcode you can still gain access by entering a universal code.

If you have forgotten the current passcode a code of “15” will always allow you to enter the Supervisor area.

Using the Supervisor menus go to the PASSCODE section and reset the operator or Supervisor passcode using the “15” code as the old number when asked.

Page 36 of 44

14.0 PERIPHERALS

The peripherals that can be used with the balance are the following:

14.1 DENSITY DETERMINATION KIT (for 0.001g units only)

The Density Determination Kit includes everything needed to carry out precise and repeatable measurement. The kit allows a sample to be weighed in air and then a liquid to determine the density of the sample. It also allows a glass sinker of known volume to be weighed in air or in a liquid, to determine the density of the liquid.

14.2 ANTI-VIBRATION TABLE

The anti-vibration table is a support for laboratory balances that isolate the balance from vibration through the floor. The table has a granite surface for the balance with a separate table top surrounding the balance.

14.3

ADAM PRINTERS

The Adam printer is a compact thermal printer which is ideal for use with laboratory balances. There are 3 versions, one to print data as it is received from the balance, second one prints data and time along with weighing data if enabled by the balance and the other one has the ability to perform statistical analysis of the weighing results if enabled by the balance.

Page 37 of 44

15.0 SAFETY AND MAINTENANCE

CAUTION

Use the AC adapter designed by the manufacturer for the balance. Other adapters may cause damage to the balance.

Avoid overloading or dropping material onto the platform which could damage the balance.

Do not spill liquids on the balance as it is not water-resistant. Liquids may damage the case and if it gets inside the balance it may cause damage to the electronics.

Material that has a static electric charge could influence the weighing. Discharge the static electricity of the samples, if possible. Another solution to the problem is to wipe both sides of the pan and the top of the case with an anti-static agent.

16.0 TROUBLE-SHOOTING

Service of a PGW balance will generally be necessary when the balance does not perform as expected. The balances are not user-serviceable. For Service Information, see section 18.0 and contact Adam equipment or your supplier.

Problems usually fall into one of the following categories:

User Problems:

The user is asking the balance for something it cannot do or is confused by the modes and functions of a balance. It is also possible the user has set a parameter that has affected the balance operation. Resetting the parameter to a normal value will restore operation.

Mechanical Problems

The balances consist of complicated and fragile mechanical devices. They can be damaged by placing a weight on it which is too high for the balance or by dropping the balance or occasionally shipping it without taking care. The most fragile parts are the flexures. Dust, dirt, spills and other foreign objects in the balance can also cause problems.

Page 38 of 44

Electronic Problems:

These are the rarest of the problems affecting balances. If an electronic problem is suspected make sure the mechanical problems that can cause similar symptoms have been eliminated before attempting electronic repairs. With the exception of cables most electronic repairs are solved by board replacement.

The table that follows is a guide of common problems and their solutions. Note that many problems may have multiple solutions and there may be problems found that are not listed in the table. For Service Information, contact Adam Equipment or your supplier.

Mechanical problems

Balance programming

Electronic problems

*A complete inspection of the mechanics to look for sources of friction.

*Verify the A/D is also unstable. If the A/D is OK then suspect the programming of the balance. Reset parameters, check temperature compensation, and redo the calibration.

Some electronic problems can also cause this. But all mechanical problems must be resolved first.

BALANCE IS NOT ACCURATE

You must have accurate and trusted weights to test a balance. If you suspect that the balance is not accurate then you must know your weights are accurate. A balance calibrated using a bag of flour is not accurate even if it works OK otherwise.

Balance is not accurate Repeatability

Verify the balance shows the same value when the same mass is placed on the centre of the pan for a few tests.

Eccentric loading

Verify the balance shows the same reading (within a tolerance depending upon the model) when a mass is placed
