ELECTROSTATIC VOLTMETER
ELECTROSTATIC VOLTMETER ESVM 1000
The electrostatic voltmeter ESVM 1000 is a microprocessor based non-contacting voltmeter which measures the electrostatic charges on very
small objects. It is an ideal instrument for measurements on semiconductors, printed circuit boards, connector pins and other areas where a
conventional electrostatic fieldmeter cannot be used.
The ESVM 1000 comes with a high resolution sensor which provides accurate results even in very small areas.
By using the special hand held probe 7100.ESVM1000.45 also the body voltage can be measured (walking test)
• Dimension: 15 x 10 x 22 cm (W x H x D)
• Range: 0 up to ± 1 kV DC or AC (Peak)
• Accuracy: 1% of full scale
• Recommended Probe-to-Test
surface distance: 2,5 mm ± 1 mm
• Power supply: power supply 230 VAC/15 VDC
• Display: LCD-Display (4 x 20 digits)
• Sensor: Side-view probe (10 x 54 mm)
• Output: analog output
Includes:
ESVM 1000 incl. hand held probe, probe (exchangeable), Power supply, conductive carrying case,
operating instructions in German and English and calibration certificate.
For using the analog output we recommend the AD-converter type 7100.UAD1 with the software
“Digilloscope” (see page 88).

CONTACT VOLTMETER ESVM 821HH
The electrostatic contact voltmeter ESVM 821 is a hand-held contact voltmeter which measures
the electrostatic charges on very small objects/surfaces. The ESVM 821 HH measures the
surface potentials on conductive or insulative objects without charge transfer to the probe.
Therefore, measurements can be performed with high accuracy.
• Dimension: 240 mm x 140 mm x 52,5 mm (H x W x D)
• Range: 0 up to ± 2 kV DC or AC (peak)
• Accuracy: < 1% of full scale
• Input resistance: > 1 x 10
