Overview:
The Botron B9201 is designed to monitor resistance of the
operator’s path to ground. It comes with a built in audible
alarm and LED, triggering either when the operator falls out of
spec, becomes disconnected, or ground is lost. It is a xed
resistor system and is go no go, there is no calibration needed.
A full time monitoring system is necessary to reduce latency
on the assembly line.

APPLICATIONS
To be used in work environments in accordance with S20.20
standard for monitoring resistance from worker to ground. It is
recommended to use constant monitoring in work environ-
ments handling components that are more susceptible to ESD
damage.
INSTALLATION
1. Mount monitor under bench area. ** If installed this way, use
standard grounding methods
2. Plug in power supply to 115v grounded outlet & unit
3. Plug grounding wire into back of unit.
4. Plug wrist strap into monitor B9201
5. Turn switch on.
6. LED will light green if good. Time to time some people have
higher and lower resistance. You can adjust this unit by
turning the adjustment screw. If the body resistance is low
turn adjustment screw to left to increase the resistivity.
When the lamp is green it is in the correct position. If the body
resistance is high, turn adjustment screw right to
decrease resistivity. When green light comes on, that is the
correct position
7. Alarm will sound and light will go red if strap is bad. It will
also go into alarm if the ground is lost. You may turn o
alarm with on/o switch in front of unit when not in use.
8. * Alternate mounting, use snap ground on monitor, to snap
on mat. (must have 3/8”F-snap on mat)
CALIBRATION
All Botron continuous monitors part numbers above do not
need to be calibrated. They are a Go/No-go solid state, imped-
ance based, monitors with no adjustability and does not need
to be calibrated. It is always important to make sure that all
units have a proper ground. An improper ground or poor
connection will sound the alarm.
