DS LS-385 Surface Resistance Tester Static Pad Taiwan Tester Antistatic Tester

 DS LS-385 Surface Resistance Tester Static Pad Taiwan Tester Antistatic Tester

Introduction
 
1, this small pocket watch can measure the surface impedance detection, but also to measure resistance to ground, wide range, from 103 ohms /  to 1012 ohms / , an accuracy of  1/2 range.
2, DS-385 using ASTM Standard D-257 parallel electrodes sensing method, you can easily and repeatedly measure various conduction type, electrostatic discharge, Insulated surfaces.
 
Use
To measure the surface impedance, measured on the surface of the table, press the red measurement (TEST) button, continuous bright light emitting diode (LED) that indicates the magnitude of the impedance of the measured surface.
 
103 = 1,000 ohms          green LED

104 = 10 kilohms           green LED
105 = 100 kohms           green LED
106 = 1 megohm            yellow LED
107 = 10 megohm           yellow LED
108 = the megohm 100       yellow LED
109 = 1000 megohm        yellow LED
1010 = the megohm 10,000       yellow LED
1011 = 100000 megohm           yellow LED
1012 = 1000000 megohm        red LED
1012 = insulated                             red LED
 
Measuring resistance to ground
 
1, the ground wire into the ground (Ground) socket, so that the right side of the table insulated detection electrode. The alligator clip to hear from you on the ground.
 
2, measured on the surface of the table, press the measure (TEST) button, sustained glowing LED indicates the resistance value of the order on the ground. Measured value is in ohms.
 
Calibration cycle DS-385 surface impedance meter calibration method
Be calibrated every twelve months DS-385 surface impedance meter.
Adopt decade resistor box, the standard measure resistance across the DS-385 table between two parallel electrodes to test its resistance value displayed is correct.
