1. OP-02 BATTERY 
 
1-1. Using the OP-02 SLA Battery 
‰ The scale can be operated with an SLA (Sealed Lead Acid) battery that will be 
commercially available. 
‰ The scale (with no other options) can be operated with a fully charged battery for; 
LCD backlight OFF and Comparator light OFF: approximately 80 hours 
LCD backlight OFF and Comparator light ON: approximately 55 hours 
LCD backlight ON and Comparator light ON: approximately 25 hours 
‰ The battery will take about 15 hours to be fully charged. 
‰ The battery life will vary depending on how the scale is used, the ambient 
temperature and so on. 
 
 
 
 
 
 
 
 
 
Installing the battery 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
‰  Use a Yuasa Battery NP4-6 (6V, 4Ah). 
‰ There will be risk of explosion if the battery is connected
improperly or replaced with the incorrect type. 
‰ Dispose of a used battery according to the local laws and
regulations.

1. Disconnect the main power cord from the outlet. 
2. Remove the ten hexagon head screws and open the rear cover.   
Take care not to drop the rear cover or the wires connecting between front 
display and rear cover will be damaged. 
3. Loosen the screws fixing the battery support and remove it. 
4. Connect the wires inside the display pod to the battery. 
Be sure to connect RED wire to positive (+ / RED) terminal and BLACK wire to 
negative (- / BLACK) terminal. Or there is a risk of explosion. 
5. Place the battery into the rear cover and fix with screws and battery support that 
removed at step 3 above. 
6. Attach the rear cover to the front display firmly using the ten hexagon head bolts. 
7. Connect the main power cord to the outlet. 
8. Press the 
 ON/OFF   key and check that the scale works normally. 
9. Disconnect the main power cord again and check that the scale still works. 
 
Charging the battery 
‰ When the weight display shows “lb1”, the battery voltage is low in voltage and 
should be recharged. Connect the main power cord to the outlet. The charging 
process will start while the scale is powered on or not.   
‰ When the battery is getting close to the low battery, the annunciator 
(PRECAUTION AGAINST LOW BATTERY) will come on. Prepare to charge the 
battery. 
‰ The scale can be used while the battery is charging. After fully charged, the scale 
will change the charging process to trickle charge automatically. 
‰ The battery cannot be charged with the OP-04 in operation. Turn the power off to 
charge. 
‰ Charge the battery at a temperature between 0°C (32°F) and 40°C (104°F). 
Preferably 5°C (41°F) ~ 35°C (95°F) is recommended. 
‰ Charge the battery when using for the first time. 
‰ The battery must be recharged regularly if the scale is not used for a long 
period of time. Every 3 months in a warmer area and every 6 months in a 
cooler area will be needed.

2. OP-03 RS-232C / RELAY OUTPUT 
 
This interface allows the FS-i series to be connected with a multifunction printer or a 
personal computer, and the relay outputs for comparator result are obtained.   
‰ The OP-03 unit includes an interface board, a connector cable, a cable gland and 
two screws (M3x6).

1. Disconnect the main power cord from the outlet. 
2. Remove the ten hexagon screws and open the rear cover. 
3. Connect the cable from external device through the cable gland to the terminal 
blocks on the interface board. Also connect a yellow/green wire inside the display 
pod directly to “FG” on the terminal block. 
Take care not to drop the rear cover or the wires connecting between front 
display and rear cover will be damaged. 
4. Connect the connector cable included in the OP-03 to the connectors on the 
interface board and the main board inside the display pod. 
5. Fix the interface board with 2 M3 x 6 screws included in the OP-03. 
6. Tighten the cable gland and attach the rear cover to the front display firmly using the 
ten hexagon bolts. 
7. Connect the main power cord to the outlet. 
8. Set the function parameters F04, F05, F06, F18, F19 and F20 according your 
application. 
‰ The OP-03 RS-232C must have settings F18-00 and F19-0.

Data output mode (F06) 
‰ Stream Mode (F06-0)   
Data is sent continuously. The data-update rate is approximately 20 times per 
second. But for 2400 bps, it is too slow to send 20 times. If necessary, set the baud 
rate 4800 bps or more. 
‰ Command Mode (F06-1)   
The scale is controlled by commands that come from an external device, computer 
etc. See “2-3. Command mode” in detail. 
‰
 Print Key Mode (F06-2) 
When the weight display is stable, data is sent by pressing the 
 PRINT  key. The 
PRINT annunciator will turn on for a short while when the data has been sent. 
‰
 Auto-print Mode + data (F06-3) 
Data is sent if the weight display is stable at +5d (d = weighing display division) and 
above. The next transmission can not occur until after the weight display falls below 
+5d. 
‰
 Auto-print Mode +/- data (F06-4) 
Data is sent if the weight display is stable at ±5d (d = weighing display division) and 
above/below. The next transmission can not occur until after the weight display falls 
between –5d and +5d. 
 
Baud Rate (F04) 
Select the baud rate according to the device to be connected. 
‰  2400 bps (F04-0) Select 2400 bps to connect with an AD-8121. 
‰  4800 bps (F04-1) 
‰  9600 bps (F04-2) 
 
 
2-3. Command Mode 
‰ In the command mode, the scale is controlled by commands that come from an 
external device, computer etc.
