OPERATION
Preparation
1.
The heater design, temperature sensor and control circuit give good temperature control and
uniformity, but make sure that there is a close fit of the probes in the block to allow efficient heat
transfer. Contact us about an insert that more closely fits your probe or device being calibrated.
2.
Plug the power cable into the socket in the back of the unit. Connect the power cable to the
electrical supply and switch the power on. 1 = power on, 0 = power off.
3.
Clean the heater block cavity out with
shop or canned air to remove any
particulate. Next place the probe insert
into the heater block as shown using the
supplied insert extractor to minimize the
risk of damaging the heater block and/or
probe insert. Never place a hot insert into
a cold heater block or vice versa as the
insert may become jammed which will
damage both parts. Always use the insert
extractor to both install and remove the
probe insert.
4.
To prevent damage to the heater block,
insert, heaters and PRT block sensor DO
NOT use the following in or around the
block;
Oil, Thermal grease, Water
Aluminum oxide sand,
Ceramic fiber insulation or Kaowool
Setting the operating temperature
1.
To set the operating temperature required, press and hold either the up or down arrow button to
increment to the value required. The values will increment faster as you hold down the button.
2.
When you have the correct set temperature displayed the unit will start to heat or cool to that
value.
3.
Once the process value/actual temperature reaches the set point, allow the block to fully stabilize
for at least 15 minutes before performing a calibration.
4.
Upon completion of your work set the temperature to 50°C/122°F or less and allow it to cool before
transporting or moving. The block fan will kick on to provide cooling. After a safe temperature has
been reached power can be switched off and the unit unplugged.
