ESD Human Body Comprehensive Tester

M321A / M321C / M321E Type

The human body comprehensive tester is a personnel grounding tester, which accurately tests the wrist strap and anti-static shoes (foot ring) of ESD protection zone (EPA) personnel according to IEC 61340-5-1 (European standard), ANSI ESD S20.20 (American standard), SJ/T 10694 (electronic industry standard) and GJB3007A (military standard).

Features:
• Solid-state touch test buttons to keep tests accurate and extend the life of the tester
• Set the test range with the DIP code, and freely configure the control range of wristbands and electrostatic shoes
• Built-in electrostatic discharge function, which automatically discharges human static electricity during measurement
• Control signals for turnstiles or automatic doors, relays to control electronic door locks, lights, buzzers or air shower doors
• Background light reminds the indication function, locates the test button, and indicates the operation status
• Supports gloved measurements, allowing operators to test anti-static shoes while wearing gloves or finger covers
• Multi-scene installation, can be installed on turnstiles, ground vertical or wall mounting
• Adjustable alarm sound level, sound intensity is appropriate when alarming
• 3 sets of high-brightness LED status indicators to indicate high/pass/low resistance for wrist strap, left shoe, and right shoe
• Supports single and two-wire wrist strap measurements, and provides dual interfaces to improve the life of the plug and dial
• Test the pedal independently with both feet, and the left and right shoe tests are done at one time

Test scoping setting

The upper limit of the bracelet and the upper and lower limits of anti-static shoes can be set through the DIP switch on the left side of the device according to the control conditions.

ANSI/ESD S20.20-2014 Certification Requirements

Practical, but not simple ...

The panel is clearly designed and easy to read, showing low, high, and pass LEDs with large touch buttons to release static electricity and not easily damaged, and an audible alarm will sound when abnormal.

Two-legged test board

According to the requirements of the static management code, each foot needs to be measured, and the pedal is designed independently of the feet, and the left shoe and right shoe are completely tested at one time.

The two-foot pedal has a split foot pedal, a device that allows for independent verification of both feet at the same time. If many operators need to check their personnel grounding equipment, using a two-foot test pedal can save a lot of time.

Single-wire wrist strap can be tested

Before entering the Electrostatic Protection Area (EPA), the anti-static wrist strap must be tested using a comprehensive body tester to ensure that it is working properly. Model TM7302 can test single wire wrist strap / double wire wrist strap

No mechanical wear and durability

The test key uses an inner/outer metal conductor, and the test is started by holding down the finger to connect the inner/outer conductor. Solid-state test keys can be used to avoid mechanical damage.

Wear gloves or finger sleeves for the test

If you wear gloves or finger covers, the test current cannot be started due to the high resistance, and an infrared induction grip is required. * When mode only, work shoe test is supported.

Turnstile installation

ESD access control systems are compulsory, and employees must pass the ESD test before entering the workshop before they are allowed to enter.

Supporting models:
TM7302E Single loop bracelet / access control function
TM7304E Single and double loop bracelet / access control function
* The picture is shown as TM7302E

Wall-mounted

It can be conveniently fixed to the wall at the EPA workshop entry point.

Supporting models:
TM7302A single-loop bracelet / access control function is optional
TM7304A single and double loop bracelet / access control function is optional
* The picture is shown as TM7302A

Bracket mounting

The steel bracket mounts directly to the pedals, giving you the freedom to mount the tester wherever you see fit.

Supporting models:
TM7302C single-loop bracelet / access control function is optional
TM7304C single and double loop bracelet / access control function option
*The picture is shown as TM7302C

Dry node control signals

Relay terminals can be integrated with electronic door locks, turnstiles, lights, buzzers, etc. This would be an advantage if the company only wanted to let people in after they had passed the test.

Dry Contact Terminals:
Contacts 1 and 2 are normally open during standby; 2 and is normally closed. The status of each contact remains unchanged if the test fails. When the test is passed, 1 and 2 are closed; 2 and 3 are disconnected.
Relay Rated Current:
When connecting the three-roller turnstile or other electronic locks, be careful that the external current does not exceed the rated range, otherwise the relay may burn out.

Automatically discharges static electricity from the human body

The test table is groundedWhen the finger touches the test key, the static electricity of the human body can be released conductively.

During the measurement, the fingers touch the test piece to realize the automatic release of human static electricity, and ensure that the static electricity value brought by employees entering the workshop is within a safe range. There is no need for a separate static elimination device.
