Threshold setting in the 3M
™
ESD Pro is critical in identifying only ESD
events of the strength equal or above the level of importance to you.
Threshold setting is done by a small rotary/push switch on the right side of
the 3M
™
ESD Pro.
Checking the Current Threshold
Simply push the actuator of the switch inwards. One red LED will show the
current ESD event threshold. Any event equal to or exceeding this level will
produce a count and a beep, and the LED bar graph will show it in red. An
event below this level will still be shown on the bar graph in green, but no
count or sound will be produced.
Setting the Threshold
To set a new threshold, do not press the switch. Rather, move its actuator
up or down. Once the switch begins to move, one red LED appears on the
bar graph display. As the switch moves up and down, this red LED moves
accordingly and its position indicates the new theshold level.
Saving the Threshold Level
After the new threshold is set, release the switch actuator and then press it
inwards. The new current threshold is now saved. The next time you power up
your 3M
™
ESD Pro, this level will be automatically set.
