External Temperature Sensor Pt 1000; Heating With External Temperature Sensor: Mr Hei-Tec, Mr Hei-Connect - Heidolph Safe Originalbetriebsanleitung

Operation

External temperature sensor Pt 1000

(optional accessory, see chapter "Accessories and spare parts")
As soon as the external temperature sensor Pt 1000 is connected, temperature will not
be measured and controlled at hotplate but directly at sensor. (Connection see chapter
"Assembly, Connect temperature sensor Pt 1000").
Heating with external temperature sensor:
MR Hei-Tec, MR Hei-Connect
When external temperature sensor is connected, 2 additional functions are available:
▪
Heating up "Fast" or "Precise":
Fast mode: speeds up heating to set temperature (factory setting) when shortest
heating up time is important.
Precise mode: enables heating up without overshooting for temperature-sensitive
samples.
▪
Calibrate:
This function allows to change the temperature measured by sensor in a range of
-5 °C to +5 °C.
Selecting heating mode
✓ Sample is positioned on hotplate.
✓ Temperature sensor is connected and inserted in sample.
✓ Required temperature is set.
➜ Press heating button.
✓ Heating button starts blinking.
For reliable measurement the temperature sensor has to be inserted
at least 20 mm into sample.
Warning:
Risk of burning! Possible damage of device
If temperature sensor is not inserted in sample the sensor measures
and controls ambient temperature. The hotplate keeps up raising
temperature till max. temperature of 300 °C but set temperature can
never be reached.
If temperature sensor Pt 1000 is connected always insert sensor in
sample before heating is started.
