Description
IONSTAT E-HST002 Megohmmeter
Product Description
The IONSTAT E-HST002 Megohmmeter kit measures surface resistivity, resistance,
temperature and humidity. It is designed to test conductive, anti-static, and static
dissipative 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 & ANSI/ESDA-S11.11. The
five pound electrodes can be externally connected for tests according to IEC 61340-4-1,
ANSI/ESDA S4.1 & ANSI/ESDA S7.1.
IONSTAT E-HST002 Megohmmeter Includes:
Tester
Two 5lb probes
One ground cord
Two accordion cables (stereo to banana)
110-220V DC power adapter*
Foam lined carrying case Certificate of calibration
INTRODUCTION
The IONSTAT E-HST002 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, foot wear, 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 five pound electrodes, the meter's test values for
resistance are in ohms (although they are displayed in ohms/sq.).

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 the measured value falls within, the IONSTAT E-HST002 will show the
actual value.

21 ohms (2.1 x 107) is displayed as 2.1 e07 ohms/sq
TEST VOLTAGE
The test voltage ranges 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
100 volt 106 - 1011 ohms per square Dissipative
100 volt 1012 > ohms per square Insulative
