Analysis Mode
Analyzis Mode simply displays any control
power that is being sent to the circuits that your
leads are connected to. The red LED’s will
indicate the level of AC power available at the
equipment. Yellow component LED’s will illu-
minate on each circuit that is currently ener-
gized. This mode is often used by a tech to
isolate the general area of a problem.
For instance, you turned the FAN switch on at
the thermostat, but the fan does not start.
Observing a lit yellow LED in the FAN section
of the
ZebraStat connected to the equipment
would tell you that the signal is getting to the
equipment (suggesting a problem inside the
equipment). If the corresponding LED was
not lit, (the signal was not getting to the equip-
ment) it suggests that the problem may be in
the thermostat or it’s associated wiring.
1) Turn all of the
ZebraStat’s component
switches to OFF, and put the Mode Switch in
the ANALYZE position.
