a. Operating with an electronic contact thermometer
An electronic C-Thermometer can be directly connected to the 5-pole
socket at the back of the appliance. The necessary power for the contact
thermometer will be supplied over this socket.
The required temperature should now be adjusted on the contact
thermometer (see the contact thermometer operating instructions).
b. Operating with a mercury contact thermometer
When operating with a mercury contact thermometer, our cable (Order
No.. SK 85) must be connected to the thermometer.
Please make sure that the heating output approximately matches the
heat-requirement, this can be adjusted with the power regulator (turning
knob 10-100%), High surplus heating output always results in post-
heating. The more precise the heating output adjustment is, the more
exact is the temperature tolerance.
c Operating with a temperature cut-out, Timeswitch, etc..
Instead of the bridge between 3 and 5, other contact-giving devices may
be connected that will switch off the heating when the contact has been
opened.
When using a temperature cut-out please make sure that the cut-out has
a thermal contact to the medium being heated
Please note that
no
external voltage should be used on the contact
socket.
Information: the contact-thermometer socket is fitted with 12 V (galvanically
separated).
4.) USE AS SAND BATH
Please order our special stainless steel cups available under Order No. SA
14 for SGK1-6 and Order No. SA18 for SG 1-7, Sand is a poor heat
conductor, which means a decrease in temperature between 50°C and 80°C
per 1 cm sand. Therefore put the vessels deep into the sand in order to ease
the heating.
5.) MAINTENANCE
Except occasionally cleaning there is no maintenance necessary.
