TEST / Element Test
Test the Heating Elements and Relays
This test is useful when measuring the wall receptacle
voltage under load, and amperage with an ammeter. On a
multiple-zone kiln, the test helps determine if the relays
and thermocouples are wired to the correct zones. If you
test thermocouples with a cigarette lighter or other heat
source, use this option.
Pointer:
Raising the thermocouple temperature
fast with a lighter or propane torch may cause an
[FE4]
error. This will not harm the controller,
though. See page 28.

[POWR]
will appear, alternating
with kiln temperature. The elements will turn on
for two minutes. Press any key to abort the test.

[TOP]
will appear, alternating with
the temperature of the top zone. The elements will
turn on for two minutes. Then
[MID]
will appear,
with temperature for the middle zone, and
[BOT]
with temperature for the bottom zone. (A
two-zone kiln shows only
[TOP]
and
[BOT]
temperatures.)

During the two-minute test, press any key to end a
zone test. The controller will then begin to test the
next zone.
AOP Outlet
After the above test, kilns equipped with the AOP outlet
will display
[J3-3]
for two minutes to test power to the AOP
outlet. If your kiln has 2 AOP outlets, the second AOP will
turn on after the first.
RST / Reset
Reset the Controller to Most Factory Defaults
Reset the controller to a known state in case the control-
ler locks up, the memory is corrupted, or you have made
many changes and would like to clear your settings.
Reset does the following:
I
Resets the LOCK passcode to 3.
I
Selects Type-S thermocouple.
I
Selects °F.
I
Erases a cone offset.
I
Erases a thermocouple offset.
I
Erases Ramp-Hold User programs stored in memory.
I
Changes Temperature Deviation
[TEDE]]
back to the
factory setting of 100°F / 56°C.
CAUTION:
If your kiln uses a Type-K thermo-
couple, the Sentry will underfire after a reset! Use
the Thermocouple Option (page 21) to select
Type-K again.

and
[F / C]
op-
tions to be sure your controller is set for the correct
thermocouple type and fahrenheit or celcius.
Multiple-Zone Options
These options appear only on multiple-zone kilns.
DIFF / Zone Temperature Difference
View Maximum Temperature Spread
For a 2-zone or 3-zone kiln, this option shows tempera-
ture difference between the top and bottom zones. If the
temperature shown is larger than expected, go to option
T123 to view the temperature of each zone.

Press
OPTIONS
repeatedly until
[DIFF]
appears.
Press
ENTER
.

The maximum difference in temperature between
the top and bottom zones will display. (Example:
[-003]
= 3°)
