Section 1 - Introduction

Your CL900A/CL950A hot point“ Thermocouple, RTD and thermistor Probe
Calibrators have been designed for ease of use and reliability whenever you
have the need to test or calibrate temperature probes. It is important that you
read this manual completely and follow all safety precautions before operating
this instrument.

1.1 Precautions

• Follow all safety precautions and operating instructions outlined in this
manual.

• Never leave your calibrator unattended when in use.

• Keep out of reach of children.

• Never touch the probe well area when hot.

• Never place any object within 3 inches of the probe well opening when hot.

• Do not operate in flammable or explosive environments.

• Never operate with a power cord other than the one provided with your unit.

• Remove and or disconnect main power cord before attempting any
maintenance or fuse replacement.

• Do not connect and or operate this unit to a non-grounded, non-polarized
outlet or power source.

• Do not connect the serial port or reference probe port to equipment with
exposed, hazardous, live voltages.

NOTE:

There are no user serviceable parts inside your unit. Attempting to repair or service your unit
may void your warranty.

1.2 Safety Warnings and IEC Symbols

This device is marked with international safety and hazard symbols in
accordance with IEC 1010. It is important to read and follow all precautions and
instructions in this manual before operating or commissioning this device as it
contains important information relating to safety and EMC. Failure to follow all
safety precautions may result in injury and or damage to your calibrator. Use of

1.3 Statement on Marking

It is the policy of OMEGA to comply with all world-wide safety and EMI/EMC
regulations that apply. OMEGA is constantly pursuing certification of its
products to the European New Approach Directives. OMEGA will add the CE
mark to every appropriate device upon verification of compliance.

1.4 General Description

The CL900A and CL950A are a part of a family of calibrators which allows for
calibration of thermocouples, thermisters, RTD and thermistor probes quickly
and easily with an accuracy to 0.8°C (1.5°F).

An integral RTD sensor assures high measurement accuracy and repeatability. A
built-in microprocessor-based PID digital controller assures exceptional stability.
Setpoint and actual temperature are displayed, simultaneously. Temperature can
be set in one degree increments from 22°C (40°F) above ambient temperature to
482°C (900°F).

The CL900A differs from the CL950A only with regard to the probe well. The
CL900A has a removable, single-port well insert. The CL950A has a built-in
multiport well. The CL900A is shipped with the CL906 insert (diameter=1/4",
depth=6"). The CL900A-230 is shipped with the CL906-M insert (diameter=4.5
mm, depth= 152.4 mm).

Figure 2. Probe Well Inserts for the CL900A

As shown in Figure 1, various inserts may be ordered from OMEGA to meet
your specific probe requirements. The insert slides into the probe well of the
CL900A.

Figure 3. CL900A Probe Well

The CL950A and CL950A-230 have permanently fixed multi-port wells that
accepts 4 different probe sizes. The CL950A and CL950A-230 has 4 standard inch
holes with diameters: 1/16", 1/4"x 2, 1/8", 3/16" with 6" hole depth. The
CL950A-M and CL950A-M-230 has 4 standard metric holes with diameters: 2
mm, 3 mm, 4.5 mm, and 6 mm x 2 with 152.4 mm hole depth.

2.1 Unpacking

Remove the packing list and verify that you have received all your equipment. If
you have any questions about the shipment, please call our Customer Service
Department at

1-800-622-2378 or 203-359-1660

Website: http://www.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.

NOTE:

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

The following items are supplied in the box: The following items are supplied in
the box:

*A probe well insert is only included with Model CL900A or CL900A-230.

2.2 Mounting

Mount the unit on a bench, table top or shelf in a horizontal position and operate
at least ten inches from any air obstructions to the fan, front panel, rear panel,
bottom and top of the unit, in an ambient environment between the specified
5°C to 38°C (40°F to 100°F).

2.3 Ambient Temperature

The CL900A/CL950A is designed to operate within an ambient temperature
range from 5°C to 38°C (40°F to 100°F). Failure to operate the unit within this
range may damage your unit. If the unit is operated in an ambient temperature
above 38°C (100°F) a thermal cutoff switch will cut off power to the heater. The
process variable (PV) will no longer approach the setpoint variable (SV). The
heaters will cool down and cease to operate. If this should occur you should
send your unit back to OMEGA for service.
