1. Introduction

The REC heating plate with ceramic plate, is used in the laboratory for general use and for all those applications that require
a precise regulation of the heating plate temperature.
The ceramic heating plate (1) means that higher temperatures can be obtained compared to the traditional aluminium
heating plate and it takes less time to heat the sample. Ceramic is an inert and very hard material and is resistant to almost
any type of chemical or mechanical aggression; it's surface characteristics remain unaltered over time.
The instrument is turned on using the ON/OFF button (2). The temperature (4) of the heating plate is adjusted using the
relative knob on the front panel, the value is indicated on the digital display (3).
NOTE: If the heating function is used the vessel must be made of a suitable material to withstand the foreseen temperature.

REC Heating Plate

2.1 Electrical connections

After having unpacked the instrument, place the unit on the laboratory bench.
Before connecting the instrument to the power supply, make sure that the values on the rating plate correspond to those of
the power supply. The equipment shall be connected to a power socket with protective earth connection, using only the
power supply cord provided with the instrument.
Ensure that the socket and the relative cut-off device conform to current safety norms and are easy to reach.
NOTE: the mains cable must remain far away from the hot plate.

2.2 Start-up

Rotate the temperature knob completely to the left. Place the flask containing the sample. Then, set the temperature by
turning the knob.

3. Operating controls

3.1 Turning on and regulating

Connect the unit to mains. In the next 5 seconds, displays shows the software version and the restarting mode (A or b,
chapter "Setting mode") and turn it on using the on-off button. The green led indicates that the instrument is On.
To start the heating function turn the heating knob "Heating °C" on the front panel. Temperatures of from 5 to 550 °C can be
selected at 5 °C intervals. The temperature setting is shown on the display. When heating is turned Off (Heating knob OFF)
and the heating plate temperature exceeds 50 °C, the message "Hot" flashes on the display until the temperature of the
heating plate falls to below 50 °C (or until the instrument is turned off using the ON/OFF).
NOTE: this warning is not active if the instrument is not connected to the power supply.
NOTE: in case of black-out, once the power is back the device will restart in the restarting mode set (OPt tyP), selected in
chapter "Setting mode".
The knob on the front panel is easily accessible and is well away from the heating plate in order to ensure maximum
operator safety as well as safeguarding the electronic components inside the unit.

3.2 Setting mode

Turn the knob twice from the minimum to the maximum during the visualization of the software version in order to enter into
the setting mode.
Once there, by turning the knob, it is possible to pass from one of the following parameter to the next ones:
