Xtester-ACL800A Probe Type Surface resistance/resistivity tester,ESD Resistance tester, for small size tested samples
Overview
The ACL800 Series(ACL800A-Probe Type and ACL800B-5-lb probes) Megohmmeter kit measures surface resistivity, resistance, temperature and humidity. It is designed to test conductive, dissipative, and insulative surfaces for electrical resistivity/resistance according to EOS/ESD, CECC, ANSI, ASTM and UL test procedures. The internal parallel electrodes comply with DIN EN 100 015/1 and ASTM D257. The 5- lb electrodes can be externally connected for tests according to IEC 61340-4-1, ANSI/ESDA S4.1 & ANSI/ESDA S7.1. Optional concentric ring probe will allow compliance to ANSI/ESDA S11.11. The ACL 800 Megohmmeter is a dependable and easy-to-use audit kit for conductive and dissipative surfaces. This meter is designed to be used in all facets of material production including engineering, maintenance, quality control, incoming inspection, manufacturing, research, or sales departments for the testing of anti-static mats, floor finishes, paints, wrist straps, smocks, footwear, bags and containers. When using the built-in electrodes, the meter’s test values for surface resistivity are in ohms per square. When using the external 5-lb electrodes, the meter’s test values for resistance are in ohms (although they are displayed in ohms/sq.). |
ACL 800 Megohmmeter Includes:
| ACL800A-Probe Type | ACL800B-5-lb probes |

TECHNICAL PARAMETERS
Resistivity: | 103 -1012 ohms/sq. |
| Resistance: | 103 -1012 ohms |
| Relative Humidity: | 10% - 90% |
| Temperature: | 32°F to 100°F or 0°C – 37.7°C if Celsius model was purchased |
| Measuring voltage: | 10v and 100v |
DECADE SCALE
103 = 1 kilohm 104 = 10 kilohms 105 = 100 kilohms 106 = 1 meg ohm 107 = 10 meg ohms 108 = 100 meg ohms 109 = 1000 meg ohms 1010 = 10,000 meg ohms 1011 = 100,000 meg ohms 1012 = 1,000,000 meg ohms |
| The test value is indicated on the LCD display. Unlike meters with LEDS that indicate only the decade within which the measured value falls, the ACL 800 will show the actual value. 27 meg ohms (2.7 x 107) is displayed as 2.7 e07 ohms/sq |
TEST VOLTAGE
The applied test voltages are 10v and 100v. According to ESDA standards S4.1, S7.1, and S11.11 one should choose 10v for conductive surfaces less than 106 and 100v for materials 106 or greater. If the meter cannot apply the correct voltage automatically, it will advise you to change to the proper setting manually. Use the switch in front of the meter to change voltage setting. As defined by the ESD Association, values indicate the following |
Voltage | Range | Definition |
10 volt | < 106 ohms per square | Conductive |
10 volt | 106 – 108ohms per square | Dissipative |
100 volt | 106 – 1011 ohms per square | Dissipative |
100 volt | > 1011 ohms per square | Insulative |
Notes
| 1,The EOS anti-static standard range is 106-1011, but usually 106-108 is better for anti-static. |
Multiple different detection methods
Heavy Hammer TestAccording to the measurement requirements, when placing two heavy hammers on the surface of the object to be measured, be careful not to cross or wrap the connections together. When measuring, do not touch the heavy hammers, leads, and the object to be measured with your hands. | |
 | Crocodile Clip TestUsed for measuring objects that are relatively small or have irregular surfaces. Connect the crocodile clip to the socket and use the crocodile clip to clamp the object for measurement. |
Parallel Electrode TestingPlace the instrument on the surface of the object to be tested, hold down the test key, and test the surface resistance, conductivity, surface insulation, humidity, and temperature of the object through the two parallel electrode fast keys of the tester. |  |
