Section 1 - Introduction

1.1 Description

OMEGA’s hot point®Calibrator is a portable, solid state controlled instrument
designed for easy on-site calibration of temperature sensors. The hot point
Calibrator is designed for portability, low cost, and ease of operation. When used
properly, the instrument will continue to provide accurate calibration of
temperature probes and sensors including thermocouple, RTD, and thermistor
probes.

The following models are available:

• The dual LED front panel display provides a clear view of both the block and
setpoint temperatures.

• You can easily set any temperature within the unit’s operating range using the
front keypad.

• A precision platinum RTD sensor controls the calibrator’s block temperature.

• The calibrator’s over-temperature multiple fault protection devices ensure both
user and instrument safety and protection.

To take full advantage of the calibrator’s many features, be sure to read the
operating procedures in Section 5 of this manual.

1.2 Technical Overview

• The hot point Calibrator features an aluminum-bronze block, which is
uniformly heated by four strategically located heaters.

• A powerful microprocessor-based digital PID auto-tune temperature controller
regulates the temperature.

• The calibrator is ready for use; optimum control parameters have been factory
programmed into the temperature controlling device. However, if you wish
to fine tune the calibrator for a particular operation, you may auto-tune the
PID parameters. Refer to Section 6, Changing the Controller Parameter.

1.2.1 CL900

The CL900 has a 6" deep test well that accepts a variety of optional inserts. These
inserts are sized to provide the best thermal contact with the test probe.

• The CL900 is shipped with an insert having a

• Optional inserts are available with 4" and 6" depths, for
probe diameters (see Section 10.2 for part numbers).

• An undrilled insert is also available, which can be drilled to the required well
diameter.

Order additional inserts separately as required for other diameter probes. For all
probes over 7" long, 6" depth wells are the best choice. See Section 10.2 for part
numbers.

1.2.2 CL950

The CL950 has a 6" deep built-in test well which accommodates 1⁄16", 1⁄8", 3⁄16", and

two,

⁄4" temperature probes. The multiport design allows you to:

• Calibrate more than one probe at a time.

• Use a pre-calibrated (or NIST traceable) probe and meter as a standard while
calibrating other probes.

Section 2 - Unpacking

Remove the Packing List and verify that you have received all equipment. If you
have any questions about the shipment, please call the OMEGA Customer Service
Department at 1-800-622-2378 or 203-359-1660. We can be reached on the internet
at omega.com; e-mail: [e-mail]

When you receive the shipment, inspect the container and equipment for any
signs of damage. Note any evidence of rough handling in transit. Immediately
report any damage to the shipping agent.

NO

The carrier will not honor any claims unless all shipping material is saved
for their examination. After examining and removing contents, save packing
material and carton in the event reshipment is necessary.

Check the shipping box to be sure you have received the following items:

Section 3 - Safety

WARNING:

• NEVER touch the heated calibrator or probes without
proper protection.

• NEVER place any object (other than the CL900 insert)
into the CL900 block.

• NEVER use a voltage other than that for which your
unit is rated.
Use on a 50/60 Hz grounded outlet.

• NEVER replace either of the fuses with one of a current

rating greater than the original.

• NEVER unplug the heated calibrator until it has cooled
down to under 149°C (300°F).

• NEVER set objects on top of the calibrator.

CAUTION:

• DO NOT use the calibrator in excessively dusty or dirty

environments or near liquids.

• DO NOT attempt to alter the programmed constants (other

than the PID parameters discussed in Section 6).

• DO NOT turn off the power switch until the heated

calibrator has cooled down to under 149°C

(300°F).

COOL-DOWN PROCEDURE

• KEEP THE CL900 PLUGGED IN WITH THE POWER SWITCH ON DURING COOL-DOWN,
SO THAT THE COOLING FAN WILL OPERATE CONTINUOUSLY.

1. Change the setpoint to 149°C (300°F) or lower, and allow the unit to cool down to
this temperature. When the CL900 has been operating in the 427°C to 482°C
(800°F to 900°F) range, it will take approximately one hour and 15 minutes to cool
down to 149°C (300°F).

2. You may unplug the unit without causing damage when it reaches 149°C (300°F).
If you turn off the power switch before reaching 149°C (300°F), the cooling fan
will still operate intermittently. This allows the unit to cool down safely. However,
when the CL900 has been operating at 482°C (900°F) and the power switch is
turned off, cooling down to 149°C (300°F) can take as long as two hours.

• DO NOT UNPLUG THE CL900 WITH THE TEMPERATURE ABOVE 149°C (300°F) OR
SEVERE DAMAGE MAY OCCUR.

CL900 and CL950 hot point®Calibrators

CAUTION:

• ALWAYS use the special tongs provided with the CL900 to
remove the insert.

• ALWAYS follow the proper procedure for cooling down the
calibrator (below).

• Operate the calibrator at ambient temperatures between 5°C and 38°C (40°F and 100°F).

• Leave at least 230 mm (9") of space between the rear of the calibrator and nearby objects
for air circulation. Keep the area around the instrument neat and clean. Position the
calibrator as shown in Figure 3-1.

• The calibrator is a precision instrument. Although it has been designed for
optimum durability and trouble-free operation, it must be handled with
care.

• The calibrator generates very high temperatures. Probes can be very hot when
removed from the well. Take precautions to prevent personal injury or
damage to objects in the area.

• Allow the block to cool before exchanging CL900 inserts (see Section 7). Use the
special tongs that are supplied with the CL900 to remove the insert. Never
place anything (other than one of the CL900 inserts) into the CL900 block.

• Keep the calibrator connected to a live power source during the cooling period.
If the power switch is turned off while the calibrator is still warm, the
thermal sensor will automatically activate the cooling fan to insure a proper
cool-down. DO NOT unplug the calibrator while it is still above 149°C
(300°F); this may cause irreversible damage to the unit.

• The calibrator is equipped with two fuses, the fan fuse and load fuse.

- If either fuse should blow, first replace the defective fuse. Never replace

either of the fuses with one of a current rating greater than the original.

- If the fuse blows repeatedly, there is probably a problem with a component

in the calibrator. In this case, contact the OMEGA Customer Service
Department. To replace either fuse, unplug the calibrator. If the unit is
hot, restore power to the fan as quickly as possible to prevent internal
damage. See Section 9.3 for more details.

• The hot point Calibrator is pre-programmed and factory calibrated for
optimum performance. Refer to Section 6 for changing the factory preset
parameters.

• The calibrator cannot be field-calibrated. If you suspect that the unit is out of
calibration or in need of repair, contact OMEGA for assistance. Do not
attempt to alter the programmed constants (other than the PID parameters
as discussed in Section 6).

• Two thermal sensors provide over-temperature protection for the hot point
Calibrator. These sensors are strategically located on the calibrator’s block
cooling jacket. If the temperature exceeds normal limits, these sensors turn
off power to the heaters. Both sensors reset automatically when operating
conditions return to normal.
