Calibration

To Check Kettle Temperature Control Calibration:
1. Move unit to an area with no wind.
2. Turn temperature control to 400° F (204° C).
3. Agitate material for 4 to 5 minutes.
4. After control has reached steady state temperature
and burners do not cycle more than once per min-
ute, insert remote calibrated temperature probe in
material and directly adjacent kettle temperature
control probe.
5. Compare temperature of remote calibrated tem-
perature probe to temperature setting on tempera-
ture control.

6. If the temperature control setting is lower than the
remote calibrated temperature setting on tempera-
ture probe, turn adjusting screw clockwise. Every
1/4 in. turn will change temperature 35° F (19.4° C).
7. If the temperature control setting is higher than the
remote calibrated temperature probe, turn adjusting
screw counterclockwise--every 1/4 in. turn will
change temperature 35° F (19.4° C).
8. Recheck calibration by turning temperature control
to 410° F (210° C) and repeat steps 3-7.
