4. SETTING UP 4-1. Setting up your scale 1. Adjust the level of the scale using the leveling feet. Use the bubble spirit level to confirm. The bubble should be in the center of the circle. 2. Calibrate the scale before use. See “7. -
Page 9: Power Source
4-2. Power source As the power source, the AC adapter or lead-acid battery is available. The scale remains powered while the AC adapter is connected, even if nothing is shown in the display. To ensure stable weighing, keep the scale connected to the power supply using the AC adapter whenever possible. - Page 10 1. Remove the AC adapter plug from the AC adapter jack. 2. Loosen the M3 screws that secure the battery cover and remove the battery cover. 3. Connect the cables in the battery compartment to the battery, the red cable to the + terminal and the black cable to the - terminal. ...

Page 11: Operation
5. OPERATION 5-1. Turning the power ON and OFF 1. Press the ON/OFF key to turn the power ON. All the display symbols appear as shown above. (As for weighing units: Only the units stored in memory are displayed.) The display turns off except a weighing unit and a decimal point. The scale waits for the weight value to become stable, and zero is displayed with the ZERO indicator (power-on zero). -
Page 12: Weighing Units
5-2. Weighing units The most common unit of weight used around the world is the gram, but there is often a need to shift to alternative units specific to the country where the scale is used or to select modes such as counting or percent. The units and the order they appear in the display are as follows: Percent mode Counting mode... -

Page 22: Gravity Acceleration Correction
7-4. Gravity acceleration correction When the scale is first used or has been moved to a different place, it should be calibrated using a calibration weight. But if a calibration weight is not available, the gravity acceleration correction will compensate the scale. Change the gravity acceleration value of the scale to the value of the area where the scale will be used. -

Page 28: Rs-232C Serial Interface
9. RS-232C SERIAL INTERFACE The scale is a data circuit-terminating equipment (DCE). Connect the scale to a data terminal equipment (DTE) such as a personal computer and external devices using a D-Sub 9-pin straight through cable. The RS-232C serial interface has the following four modes. Stream mode Outputs data continuously. - Page 29 Pin assignments Direction Signal name Pin No. Description DCE-DTE – – N.C. → Transmit data ← Receive data – – N.C. – Signal ground → Data set ready ← Request to send → Clear to send – – Used internally Signal names of the scale side are the same as the DTE side with TxD and RxD reversed Scale (DCE)
