ACL 350

Application and Use Instructions for Product: # 350 Digital Static Locator
 

ACL MODEL #350
CALIBRATION PROCEDURE

Laboratory instruments used for this procedure:

1. ETS 810 High Voltage(0-10KV) Power Supply
2. Simco EA-2 Charge Plate Monitor (6x6 inch plate) OR Prostat CPM-760 6" Plate
3. Floating Power Supply- Tenma 0-30 volt DC Maximum
4. Laboratory Test Fixture with Instrumented Clamp Holder
5. Instrument to be calibrated- ACL 350
6. Personnel Grounds - Tested

 

Procedure:

1. Attach the ETD 810 Power Supply to the EA-2 6-inch plate using the high voltage lead provided.
2. Place the ACL 350 instrument into the test fixture clamp
     a. The instrument sensor should be exactly 1 inch away from the 6-inch plate
     b. The ACL 350 should be 6 inches above the calibration table
3. Adjust the floating power supply to approximately 9.2V DC
4. Turn on the ACL 350 by pressing the power button

NOTE: The ACL 350 has a built in time out function, approximately 60 seconds. After
the power switch is pushed, the unit will turn itself off in 60 seconds. Before each test
reading, push the power switch to reset the time out function. Before each test, reading
the ACL 350 must be re-zeroed to ground. Ground the CPM target plate and push the
ground button twice to obtain a zero display.

5. Ramp up the ETS 810 Power Supply Voltage to positive (+) 1KV. This voltage is being applied to

the 6-inch plate through the high voltage cable.
6. Observe that the instrument measurement being displayed is plus or minus 5% of the applied

voltage (+1KV +/-5%).
7. If so, document the measurement in the correct spot on the calibration sheet.
8. If not, unit is out of calibration and needs to be returned for sensor replacement.
9. Turn ETS Power supply off.
10. Push the power button to reset the 60 second time out function on the ACL 350 and re-zero as

noted before.
11. Ramp up the ETS Power Supply Voltage to negative (-) 1KV. This voltage is being applied to the

6-inch plate.
12. Observe that the instrument measurement being displayed is plus or minus 5% of the applied

voltage (-1KV +/-5%).
13. If so, document the measurement in the correct spot on the calibration sheet.
14. If not, unit is out of calibration and needs to be returned for sensor replacement.
15. Turn ETS Power Supply off.
16. Push the power button to reset the 60 second time out function on the ACL 350 and re-zero as

noted before.
17. Repeat steps No. 5 through No. 10 at +/-5KV
18. Repeat steps No. 5 through No. 10 at +/-10KV.
19. LOW BATTERY TEST:
       a. After all tests are finished and documented unit should be tested for low battery display on

the LCD
       b. Lower the voltage on the Tenma Floating Power supply to less than 7.2 volts.
       c. The low battery display should come on to less than 7.2 volts.
       d. Adjust the Tenma Floating Power Supply to greater than 7.2 volts.
       e. The low battery display should go off when the voltage reaches greater than 7.2 volts.
20. After all procedures are successfully completed and documented, place a calibrated sticker on the

instrument.

NOTE: NO INTERNAL ADJUSTMENTS CAN BE MADE TO THESE UNITS. AT ANY
POINT IN THE UNIT FAILS A PROCEDURE, THE UNIT MUST BE RETURNED FOR
SENSOR OR BOARD REPLACEMENT.

ACL-350静电电压测试仪
 
 
ACL-350静电电压测试仪是世界上体积小的袖珍式非接触数字式静电测量表。
 
ACL-350静电电压测试仪可以测量物体表面的静电压值和静电压极性。
 
ACL-350静电电压测试仪操作简单，带有测量保持钮和置位钮。
 
ACL-350静电电压测试仪具有自动关机功能，超过90秒钟不使用则自动断电。
 
ACL-350静电电压测试仪是通过防静电材料表壳形成接地通路，因此，在测量过程中操作人员无需戴防静电

腕带。3位半的数字显示电压值是通过每秒钟取样三次而连续更新的测量值。显示的测量值与表与被测物体

的距离相关。
 
ACL-350静电电压测试仪的应用:
 
包装材料，泡沫材料，包装薄膜和包装袋。
 
生产线上的辅助性器材，如：器具、周转箱、工具、胶带和卷状材料。
 
原材料：塑料、镜头、器具箱、元器件箱、器材柜等。
 
人员：体静电、防静电服、超净防静电工衣。特性：
 
3位半液晶数字显示，自动显示测量静电压值。
 
长度为25.4毫米（1英寸）测量标尺适用于进行重复性静电压测量。
 
自动辨别静电压极性，当带静电物体表面为负极性时，可显示出负极性。
 
电池容量指示 ″BAT″。 ?测量值取样保持钮。

重量 5盎司
 
尺寸 107毫米×61毫米×23毫米
 
 
ACL-350静电电压测试仪使用须知：
 
被测量物体表面尺寸必须大于测量距离。为获得真正的测量值在测量距离为25.4毫米时，被测物体尺寸不

能小于127毫米×127毫米。
 
可用柔软的布蘸酒精清洁ACL 350的测量电极。
 
可使用ACL-350静电电压测试仪进行测量时，首先操作人员确保自身对地放电，表外壳为防静电材料制成。

将表的测量电极对准待测物体表面，按下置“0"按钮。保持与待测物体表面距离为25.4毫米（1英寸）。 按

下测量钮，读出测量结果。 被测物体的静电压值如为负极性，LCD上显示“-"。正极性时无显示符号。 如果

在超过25.4毫米距离下测量值超过20,000伏，请停止，这时的带静电物体可能会产生电弧放电，任何测量

均需小心谨慎。
