ESD walking test kit SFM PRO WT with field meter and case

The SFM PRO WT extends the Safeguard electrostatic field meter with the MK voltage probe to form an ESD walking test kit. It checks that a person is correctly grounded so static electricity is drained away and the risk of ESD damage to sensitive components is reduced. The kit consists of the MK voltage probe, a hand electrode and further measuring accessories.

Benefits

• Measurement by the influence principle (field mill principle)
• Measured field strength is converted to charge in volts over the set measuring distance
• One-button operation with very high zero-point stability, no adjustment needed before each measurement
• Continuous battery-voltage monitoring with automatic shut-off

Technical data

• Display: two-line, 12-digit alphanumeric LCD
• Adjustment accuracy: less than 5 %
• Measuring range: 0 to plus/minus 200 kV (distance mode), 0 to 1 MV/m (field strength mode)
• Output: plus/minus 1 V (Ri greater than 1 kOhm) proportional to field strength (E-field mode only)
• Standard measuring distance: 2 cm
• Power: battery operation, approx. 10 h with alkaline battery

Scope of delivery

• Safeguard electrostatic field meter (EFM)
• ESD case with foam insert
• 1x 9V NiMH battery, plug-in charger
• MK voltage probe, hand electrode, stand
• 2 m silicone cable, crocodile clip, user manual

Applications

Used to verify personnel grounding in electronics manufacturing, repair shops and laboratories, to prevent component damage and ensure product quality.

Standards and compliance

Walking-test measurement to IEC 61340-4-5.
