3. PRECAUTIONS To get the optimum performance from the balance and acquire accurate weighing data, note the following: 3-1 Before Use Install the balance in an environment where the temperature and humidity are not excessive. The best operating temperature is about 20°C / 68°F at about 50% relative humidity. Install the balance where it is not exposed to direct sunlight and it is not affected by heaters or air conditioners. Install the balance where it is free of dust.
3-2 During Use Discharge static electricity from the material to be weighed (hereinafter referred to as sample). When a sample could have a static charge, the weighing data is influenced. Ground the balance and try the following: Eliminate the static electricity by AD-1683 as an accessory. Or try to keep the ambient humidity above 45%RH. Or use a metal shield case. Or wipe a charged plastic sample with the wet cloth.
3-3 After Use Avoid mechanical shock to the balance. Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair. Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent. Avoid dust and water so that the balance weighs correctly. Protect the internal parts from liquid spills and excessive dust.

Weighing pan Container Sample 2 Place a sample on the pan or in the container. 3 Wait for the stabilization indicator Read the value. to be displayed. 4 Remove the sample and container from the pan.
6-2 Counting Mode (PC) This is the mode to determine the number of objects in a sample based on the standard sample unit mass. Unit mass means the mass of one sample. The smaller the variables in each sample unit mass is, the more accurate the counting will be. The GX series balance is equipped with the Automatic Counting Accuracy Improvement (ACAI) function to improve the counting accuracy.
Notes If the balance judges that the mass of the samples is too light and is not adequate to be used as the unit mass, it displays lo . Do not use the samples. If the balance judges that the mass of the samples is too light to aquire accurate weighing, it displays an error requiring the addition of more samples to the specified number. In the example above, 150- pC appears, requiring 25 more samples. Add 25 samples and press the PRINT key.
6-3 Percent Mode (Pct) This is the mode to display the weight value in percentage compared to a 100% reference mass and is used for target weighing or checking the sample variable. Selecting the percent mode 1 Press the MODE key to select pct (percent mode). If the percent mode can not be selected, refer to “5. WEIGHING UNITS”. Storing the 100% reference mass 2 Press the SAMPLE key to enter the 100% reference mass storing mode. Even in the storing mode, pressing the MODE key will switch to the next mode.
6-4 Animal Weighing Mode (Hold Function) This is the mode to weigh a moving object such as an animal, even when the display of the weighing data fluctuates. The hold function allows the average weight of the animal to be displayed. To use the hold function, set the function in the function table. For details, refer to “10. FUNCTION TABLE” and “10-4 Description of the Class “Environment, Display””.
7. RESPONSE ADJUSTMENT / SELF CHECK FUNCTION This function detects the influence on weighing that is caused by drafts and/or vibration at the place where the balance is installed and sets the response characteristic automatically. When this function is selected, the balance self-checks the performance at the same time. Two modes of response adjustment are available: automatic and manual.
Notes If improper performance is found in the self check, the balance displays CH no . Contact the local A&D dealer for repair. If the automatic response adjustment fails, the balance displays CH ng . Check the ambient conditions such as breeze and vibration, also check the weigning pan. Then, perform the adjustment again. To return to the weighing mode, press the CAL key. If the automatic response adjustment is awkward, try to refine it using the manual response adjustment.

All the data in memory is available to be output at one time to a printer or personal computer. Up to 50 data sets of the latest calibration or calibration test can be stored. When the memory capacity has been reached, “fUl” illuminates.
12-4 Memory for Unit Mass in the Counting Mode The data memory function can store 20 sets of unit mass for the counting mode. Even if the AC adapter is removed, the data is maintained in non-volatile memory. Among the 20 sets, “p01” is the memory function for the standard counting mode. The unit mass in memory can be recalled and used for weighing. The unit mass in memory can be recalled and changed. Recalling the unit mass 1 Set the “Data memory ( data )” parameter to “1”.
13. UNDERHOOK The underhook can be used for weighing large samples, magnetic materials or for measuring density. The built-in underhook is revealed by removing the plastic cap on the bottom of the balance. Use the underhook as shown below. Caution Do not apply excessive force to the underhook. When not in use, attach the plastic cap to prevent dust from getting into the balance.
14. PROGRAMMABLE-UNIT This is a programmable unit conversion function. It multiplies the weighing data in grams by an arbitrary coefficient set in the function table and displays the result. The coefficient must be within the range between the minimum and maximum shown below. If the coefficient set is beyond the range, an error is displayed and the balance returns to the coefficient setting mode, prompting to enter an appropriate value. A coefficient of 1 was set at the factory.
15. DENSITY MEASUREMENT The GX series balance is equipped with a density mode. It calculates the density of a solid using the weight of a sample in air and the weight in liquid. The density mode was not selected for use when the balance was shipped from the factory. To use the mode, change the function table and activate the density mode. Two ways to set the density of a liquid are available: by entering the water temperature or by entering the density directly.
The relation between the water temperature and density is shown below. Entering the density directly ( ldin 1 ) In the density mode, press and hold the MODE key until the density currently set (unit : g / cm3, 3 factory setting : 1.000g / cm ) is displayed. Use the following keys to change the value. RE-ZERO key To set the value of the digit selected. SAMPLE key To select the digit to change the value.
Measuring procedure 1 Confirm that the balance is in the mode to measure the weight of the sample in air. (“g” displayed and processing indicator blinking) 2 Confirm that the balance indicates zero. If it does not indicate zero, press the RE-ZERO to reset the displayed value to zero. 3 Place the sample on the upper pan (in air). When the value displayed on the balance becomes stable, press the SAMPLE key to confirm the value (the weight of the sample in air).
16. RS-232C SERIAL INTERFACE / EXTERNAL INPUT RS-232C The balance is a DCE device. Connect the balance to a personal computer (DTE), using a straight through cable or a modem cable.

17-3 Using Windows Communication Tools (WinCT) When Windows is used as an operating system in a personal computer, the provided WinCT can be used to transmit the weighing data to the personal computer. The WinCT has two communication methods: “RsCom” and “RsKey”. For details on WinCT, refer to the WinCT instruction manual. The current version of the WinCT can be downloaded from the A&D website. RsCom Can transmit commands to control the balance.
5 Using the GX series balance memory function The weighing data, instead of outputting it immediately to an external device, can be stored in the balance’s memory. Later, all of the weighing data stored can be output to a personal computer at one time. 6 Using a personal computer as an external indicator With the “RsKey” test mode function, a personal computer can be used as an external weight indicator for the balance. (To do this, set the balance data output mode to stream mode.

18-4 Control Using CTS and RTS Depending on the “Ct5” parameter of “Serial interface ( 5if )”, the balance performs as follows: Ct5 0 Regardless of whether the balance can receive a command or not, the balance keeps the CTS line HI. The balance outputs data regardless of condition of the RTS line. Ct5 1 The CTS line is kept Hi normally. When the balance can not receive the next command (e.g. while the balance is processing last command), the balance sets the CTS line to Lo.
19. MAINTENANCE Do not use organic solvents to clean the balance. Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent. The mass of the internal mass may change due to corrosion or other damage caused by the operating environment, or due to aging. Check the internal mass using an external weight periodically. Do not disassemble the balance. Contact the local A&D dealer if the balance needs service or repair. Use the original packing material for transportation.
Weighing method Does the weighing pan touch the breeze ring or anything? Is the weighing pan installed correctly? Is the RE-ZERO key pressed before placing a sample on the weighing pan? Is the sample placed in the center of the weighing pan? Has the balance been calibrated using the internal mass (one-touch calibration)? Has the balance been warmed up for 30 minutes before weighing? Sample and container Has the sample absorbed or lost moisture due to the ambient conditions such as temperature and humidity?
Display Error code EC, E20 Description Calibration weight error The calibration weight is too heavy. Confirm the calibration weight value. Press the CAL key to return to the weighing mode. EC, E21 Calibration weight error The calibration weight is too light. Confirm the calibration weight value. Press the CAL key to return to the weighing mode. Overload error A sample beyond the balance weighing capacity has been placed on the pan. Remove the sample from the pan.
Display Error code Description Clock battery error The clock backup battery has been depleted. Press any key and set the time and date. The clock and calendar function works normally as long as the AC adapter is connected to the balance. If this error appears frequently, contact the local A&D dealer. Memory full (Blinking) The amount of weighing data in memory has reached the maximum capacity. Delete data in memory to store new data. For details, refer to “12. DATA MEMORY”.
Display Error code EC, E06 Description Format error A command includes incorrect data. e.g. The data is numerically incorrect. Confirm the command. EC, E07 Parameter setting error The received data exceeds the range that the balance can accept. Confirm the parameter range of the command. Other errors If the errors described above can not be released or other errors are displayed, contact the local A&D dealer. Other symbol When this indicator blinks, automatic self calibration is required.
