The test resistance limits for footwear and wrist strap tests are controlled by the DIP
switches inside the tester. For a configuration different than the default settings, remove the
unit from the sign, remove the back of the case, and reset the DIP switches inside the unit
as desired.
Footwear resistance range selection.
DIP switches 1 & 2 control the “HIGH” limit for the footwear test selection as follows:
Switch 1 Switch 2 High Limit Resistance
ON ON 10 Megohms (1 X 10
7
)
OFF OFF 35 Megohms (3.5 X 10
7
) DEFAULT SETTING
ON OFF 100 Megohms (1 X 10
8
)
OFF ON 1 Gigohm (1 x 10
9
)
*At 1 Gigohms high limit resistance, a dirty footplate could result in a false pass. When using this setting,
special care must be taken to keep the footplate clean.
DIP switches 3 & 4 control the “LOW” limit for the footwear test selection as follows:
Switch 3
Switch 4 Low Limit Resistance
ON OFF 100 Kilohms (1 X 10
5
)
OFF ON 1 Megohms (1 X 10
6
) DEFAULT SETTING
OFF OFF 10 Kilohms
The “Optional” settings allow the use of custom resistance values when installed.
Wrist strap test option selection.
DIP switch 5 must be “ON” (DEFAULT SETTING) for the wrist strap test to be active. If the
wrist strap test is disabled by DIP switch 5 being “OFF”, the 3 LEDs for this test will remain “OFF”
at all times.
The “LOW” limit for the wrist strap test is set to 1 Meghms and can not be changed by the user.
DIP switch 6 in the “ON” position (DEFAULT SETTING - USA) sets the “HIGH” limit for the
wrist strap test to 10 Megohms (10
7
). DIP switch 6 in the “OFF” position (DEFAULT
SETTING – EUROPE) sets the “HIGH” limit for the wrist strap test to 35 Megohms (3.5 X
10
7
).
