Description
The Vermason Combo Tester is a 3-state
touch tester designed for fast and frequent
testing of ESD personnel grounding devices.
The Combo Tester incorporates a unique
dual test circuit design which improves
accuracy of testing and eliminates the need
for separate wrist strap and foot grounder
test units. The 222610 is equipped with a
750 Kilohm - 35 Megohm circuit, ideal for the
testing of wrist straps and footwear.
Test parameters are factory set but can be
adjusted to match your own specifications.
The Combo Tester is very simple to operate.
A green light signals the user that everything
is OK. A red light and an audible indicator
means that the circuit resistance is either too
low or too high.
The testers each include a
convertor, which converts the
banana plug on the face of
the unit into a 10mm snap.
NOTE: Once the convertor
has been put into the plug socket it cannot
be removed.
"The primary means of grounding personnel
shall normally be by a wrist strap connected
to an EBP [Earth Bonding Point]." (EN
61340-5-1 paragraph 5.5) "Wrist straps shall
be checked before use. Each check shall
be made with the wrist band worn in contact
with the wearer's skin and with the ground
cord attached to the appropriate tester." (EN
61340 5-1 paragraph 9.6) "The wrist strap
shall consist of a band that fits snugly around
the wrist and a cord to connect the band
to an EBP...The total resistance from hand
to EBP shall be in accordance with table
1 [Rg 7,5 x 10^5 to 3,5 x 10^7 ohms]. (EN
61340-5-1 paragraph 5.2.7)

"All wearers shall check that their heel and
toe straps meet requirements. The check
shall be made before entering the EPA."
(EN 61340 5-1 paragraph 9.6.3) "When
the footwear/floor systems are used as the
primary means of grounding personnel,
the resistance of the combination shall be
determined by the ESD co-ordinator, and
is recommended to be between 7,5 x 10^5
ohms and 3,5 x 10^7 ohms." (EN 61340-5-1
