AE-780 Resistance Meter

The AE-780 is a lightweight, pocket

sized, auto

ranging surface resistance meter. It is

designed to test conductive, dissipative, and insulative surfaces for electrical resistance
according to the ESDA’s parallel resistivity probe method DIN EN 100 015/1 & ASTM
D257.

If the meter is used with the 5-lb probes available in the accessory kit, it will
comply to IEC 61340

1, ANSI/ESDA S4.1 and ANSI/ESDA S7.1.

AE-780 Resistance Meter includes:

* Tester

* Two accordion cables (stereo to banana)

* 9

volt battery

* Certificate of calibration

AE-780 Accessory Kit includes:

* Two 5

lb probes

* Foam

‐

lined carrying case

Limits

* Resistivity: 10

ohms/square

* Resistance: 10

ohms

* Measuring voltage: 10v and 100v
