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, peltiers 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. Alternatively you can press the («PF) key to move over to
individual digits to set higher values much quicker. After 2 seconds your value will be set &
retained.
2.
When you have entered a set temperature the unit will start to heat or cool to that value.
3. Once the process value temperature reaches the set point, allow the block to fully stabilize for
at least 10 minutes before performing a calibration.
4. When calibrating sensors and thermometers start at higher temperatures first and then work
down to lower ones. This will allow devices to be removed safely.
5.
Use the main insert well for calibrating sensors and thermometers. The ¼” hole behind the
insert well is for holding your reference thermometer when performing comparison
calibrations. All calibrations should be performed in the probe insert.
Entering up to 8 setpoints for fast recall
1. To input up to 8 setpoints press the first button on the left and then the 2
nd
button from the
left until the top line displays SP-0. Here you can enter up to 8 values for fast future recall. Do
not change any of the settings or values after SP-7. When finished entering values press the
button on the left one time. You’ll need to note which value is in which location for future recall.
2. To select one of the 8 setpoints for use from the main display press the 2
nd
button from the
left so the top line displays M-SP. Next use the up arrow key to select one of the 8 setpoint
values. Press the 1
st
key on the left twice for the value to be accepted.
