Unit mass in the counting mode Comparator settings Tare value Notes To change the memory data other than specified in the function table, re-set the Data memory (data)" parameter of the function table.
Step 3 Select a method. To perform a weighing using the selected memory data Press the PRINT key to confirm the selection. The balance will return to the weighing mode with the selection ready for use. To change and store the selected memory data Press the SAMPLE key to enter the storage mode. Two inputting modes are available for entering the value to be stored. Digital input mode Weighing input mode To switch the inputting mode, press and hold the MODE key.
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 cover plates on the bottom of the balance. Use the underhook as shown below. Caution Do not apply excessive force to the underhook. Weighing pan When not in use, attach the cover plate to prevent dust from getting into the balance. Pan support The weighing pan, pan support and Step1 draft gate fall off, when turnig over Step2 the balance.
14. Programmable Unit This is a programmable unit conversion function. It multiplies the weighing data in kilograms by an arbitrary coefficient set in "Programmable unit (mlt)" of 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.
15. Density Measurement The 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. Inputting order, of the parameters necessary for density measurement, can be changed. A part of the parameters can be changed and used for re-calculating the density.
15-1-2. Measuring the density Note If the liquid temperature or the type of liquid is changed during measurement, input again the value of the liquid density as necessary. Refer to "C. Entering the density of a liquid". Entering the density mode Step 1 Press the MODE key as necessary to select the density mode. When the density mode begins, "d-a" (weight in air), "g (gram)" for the unit and the processing indicator ( ) are turned on. Step 2 Selecting a parameter to set.
(B) Entering the weight of a sample in liquid 1 Confirm that nothing is placed on the lower pan (in liquid). Press the RE-ZERO key to set the display to zero. 2 Place a sample on the lower pan (in liquid). When the value displayed on the balance becomes stable, press the PRINT key. The sample weight in liquid is confirmed and the balance will return to the density mode (Go to "Step 2 Selecting a parameter to set"). 3 Remove the sample from the lower pan.
Entering the density directly (ldin 1) The density currently set (unit : g / cm3, factory setting : 1.0000g / cm3) is displayed. Use the following keys to change the value. The range to set the density is 0.0000g / cm3 to 1.9999g / cm3. RE-ZERO key ...To set the value of the digit selected. SAMPLE key ....To select the digit to change the value. PRINT key........To store the change, display end and return to the density mode. (Go to "Step 2 Selecting a parameter to set") ...........

17. Commands 17-1. Command List Note A command has a terminator added, that is specified using "5if Crlf" of the function table, and is sent to the balance. Commands to query weighing data C Cancels the S or SIR command. Q Requests the weighing data immediately. S Requests the weighing data when stabilized. SI Requests the weighing data immediately. SIR Requests the weighing data continuously. Commands to control the balance Requests the upper/lower limit value code number of the selected value.
Commands to control the balance Same as the RE-ZERO key R Same as the SAMPLE key. SMP Same as the MODE key U Recalls the unit mass values in memory. mm: 01 to 50. UN:mm Changes the unit mass value. Use "g" of unit. ~ is space mark. Example: the unit mass value is 2000.0 g. UW:∗∗∗∗∗∗.∗~~g Command: UW: +002000.0~~g When a unit is required in commands such as a "PT:" command, use the 3-digit unit code of the A&D standard format. nnn indicates a three-digit numerical value. 17-2.
17-3. 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 the condition of the RTS line. Ct5 1 The CTS line is kept Hi normally. When the balance can not receive the next command (Example: while the balance is processing the last command), the balance sets the CTS line to Lo.
18. Maintenance 18-1. Treatment Of The Balance In normal use, the balance can be cleaned with water. But, keep the following precautions so that dust and water do not invade the balance. Do not direct water pressure at the bottom of the balance. Do not use powerful water jets. Do not submerge the balance in water. Clean the balance with a lint free cloth that is moistened with warm water and a mild detergent. Do not use organic solvents to clean the balance. Do not disassemble the balance.
