Note
It is not allowed to plug in the external probe
while the temperature knob is ON. Please
turn the temperature knob to OFF state while
plugging in the external knob. Otherwise, the
display will blink and the heating element will
be turned off until reset.

When using a probe with the Isotemp unit it is
recommended that a clamp on a support rod be used to
hold the probe in the solution.
To ensure accurate probe readings, as much of the probe
sheath as possible should be immersed in the solution.
Make sure the probe is immersed in the liquid and is
not located in air or outside of the solution. If the probe
is plugged into the hot plate, but is not in solution while
the heat control is operating, the temperature display will
continue to indicate an ambient temperature, and a probe
out of solution error will occur. Because the set point
cannot be reached the heating element will continue to
supply heat to the top plate, and the maximum top plate
temperature(300°C, 400°C or 540°C) may be reached. If
the remote probe does not sense a temperature change in
three minutes the unit will display E03 and shut down.

Heating Small Volumes

Preheating small volumes is not necessary as it may cause
the temperature to overshoot the desired set-point.
Heating Metal Vessels and
Sand Baths
Isotemp is capable of precisely regulating the top plate
temperature, metal vessels and sand baths may be heated
safely without the danger of the ceramic top breaking. Use
the lowest temperature setting possible for applications
to limit thermal stress to the ceramic top. Using a metal
vessel or sand bath may reduce the life of the stirring hot
plate.
