Product Name: Surface resistance tester

 

Products: 1.ACL385 this compact mini table to measure the surface impedance monitoring can also measure the resistance to ground, wide range, from 103 ~ 1012Ω, an accuracy of ± 1 / 2 range.

 

2.ACL-385 surface resistance tester, using ASTM standard D-257 parallel to the electrode sensing method, can be simple, repeated measurement of a variety of conduction, electrostatic discharge type, insulation surface.

 

3. Use: To measure the surface impedance measured on the surface of the table, hold down the red measurement (TEST) button, and continue to shine the light-emitting diode (LED) that indicates the order of addition to measuring the surface impedance; measurement of ground resistance: the ground wire into the ground (ground) socket, so the right side of the table detection of insulation electrode (with the socket on the same side), the alligator clips to the online receipt you will be measured on the surface of the table, press live measurements (TEST) button, continue to light the LED indicates the resistance to ground should be orders of magnitude, the measurement unit is the ohm.

 

Product parameters: Power supply: 9 V PP3 alkaline battery; measuring voltage: rated 9 V; Relative Humidity: 0% to 90% (no condensation); Accuracy: ± 10%; repeat error: ± 5%; Weight: 170 grams (60Z); Size: 127 × 76 × 26mm.

 

ACL385 surface resistance meter Calibration Method: calibration cycle: to be calibrated every twelve months ACL-385 surface impedance meters, using decade resistance box, the standard measure resistance across the table in the ACL-385 to test between two parallel electrodes The impedance value displayed is correct. Parameters: Measuring voltage: 9 V; temperature range: Humidity 5 to 49 degrees Celsius; Storage temperature: -15 degrees Celsius to 60 degrees Celsius; Relative Humidity: 0% to 90% (non-condensing); measurement time: 10 orders of magnitude ; transition point: 1 / 2 log (3.16X10n); transition point accuracy: ± 1 / 2 level; Accuracy: ± 10%; Repeatability: ± 5%.

 

ACL385 table surface impedance calibration step: ACL-385 used in the table is 1% of the ultra-thin film resistors and high-speed amplifier circuit, the calibration procedure is based on the product carried out by linear circuit techniques. Impedance conversion point is 1 / 2 log that is 3.16 × 10n, the linear transition point is the median for each measurement file (mean value per unit) of ± 10%.
