Quick-CAL Range
The Quick-Cal range are designed to be fast, simple
to use and above all truly portable. Ideal for the simple
testing of temperature sensors.
OPERATION
Altering the Block Temperature, (Setpoint)
1. Switch the unit on. The power switch is located
on the rear panel.
2. The controller will briefly show its software
version before displaying an indication of the
block temperature.
3. Momentarily press either the UP or DOWN
key once to display the setpoint (desired
temperature).
4. To alter the value press and hold the UP key to
raise the value or the DOWN key to lower the
value.
5. The display will return to show the nominal
block temperature when no key is pressed for
0.5 second.
The other controller functions are hidden from the
operator. The values are pre-set and should not be
changed.
Getting Better Accuracy
For accurate calibration of sensors it is good practice
to include a calibrated reference probe in the block,
then the units under test are compared to this
reference probe.

Altering the Ramp Rate
The ramp rate or set point rate limit provides a means
of limiting the rate at which the temperature of the heat
source will increase or decrease.
Normally it is desirable to allow the unit to heat and
cool at the maximum rate possible, which is achieved
by setting the ramp rate to OFF. This is the Factory set
default value.
For some applications, e.g. testing temperature cut
out switches it can be useful to be able to program the
temperature ramp rate.
To alter the ramp rate:
1) Press the SCROLL key until Sprr is displayed.
2) The parameter can be changed from OFF to
the desired value with the UP and DOWN
keys.
3) Press the SCROLL key to return to the normal
display.
The units are °C per minute.

Electrical Supply
Before connecting to the electricity supply please
familiarize yourself with the parts of this handbook
relevant to your model.
Safe Use
Do not use in wet or damp environments.

Unpacking and Initial Inspection
Our packing department uses custom designed
packaging to send out your unit, after unpacking the
unit, to inspect it for any sign of shipping damage, and
confirm that your delivery is in accordance with the
packing note. If you find any damage or that part of the
delivery is missing please notify us or our agent, and
the carrier immediately. If the unit is damaged you
should keep the packaging for possible insurance
assessment.
Trouble Shooting
Quick-Cal Low will not reach -15°C . . .
Check ambient temperature - Quick-Cal Low
is rated for -15°C in an ambient of 20°C.
Quick-Cal High will not control at 30°C . . .
Check ambient temperature - Quick-Cal High
is rated for use at 30°C in an ambient of 20°C.

Check the switch position
Check the power supply
Check the connecting lead
Check fuse - the Quick-Cal high has a fuse
in each supply line. Fuses are accessed by
removing the front cover of the power entry
module and locate in the removable red
draw.
The temperature controller includes diagnostic
alarms that warn if an internal error occurs in the
controller.

Cautionary Note
Failure to follow these instructions could result in fatal
injury or cause damage to the product.
Isotech products are intended for use by technically
trained and competent personnel familiar with good
measurement practices.
It is expected that personnel using this equipment will
be competent with the management of apparatus
which may be powered or under extremes of
temperature, and are able to appreciate the hazards
which may be associated with, and the precautions to
be taken with, such equipment.
Your unit's supply voltage requirement is specified on
a plate on the instrument along with the serial number.
All instruments will work on an electricity supply
frequency of 50Hz or 60Hz.
The Quick-Cal low is powered from a 15V D.C. Switch
Mode power supply, or a 12V, 7Ah Battery.
Read ALL Handbooks supplied with Electrical
Accessories before use.
Quick-CAL Blackbody
The Quick-CAL Blackbody is ideal for the rapid and
portable testing of infra red thermometers. The cavity
has dimensions of 25 x 115mm with an end cone. The
emissivity is >0.99. The surface coating has an
emissivity of 0.98 and the cavity gives an overall
emissivity better than 0.99. No insert is used with this
model - the cavity is used as the target for the infra red
thermometer.
