CAUTION:

Section 3 - Operation

3.1 Important Notes On Calibrator Operation

• 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 probe well can be set to high temperatures. Probes can be very hot when
they are removed from the well. Take precautions to prevent personal injury to
yourself, others and objects in the work area.

• After inserting or removing probes into the probe well allow the calibrator

time to stabilize before making your measurement. Adding or removing
probes changes the total mass of the probe well, the controller will require time

to adjust for this change and stabilize back to the temperature you have set.

NOTE:

NOTE:

P.I.D. Control:
Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm
used in high-end temperature controllers. The controller causes the process to
attain the desired temperature by turning the process on or off. The process may
be a heater or refrigerator. As the process temperature approaches the setpoint
temperature the hot or cold process will be pulsed to reduce the corrective measures
and minimize overshooting. The controller provides a visual representation of the
process status through LED indicators. An indicator may be lit continuously, blink or
shut off entirely to indicate that the process is on, being pulsed, or off, respectively.

3.4 Overheat Reset Switch

If the unit is operated at high temperatures in elevated ambient temperatures, an
overheat condition may occur. In an overheat situation a mechanical reset switch
inside the unit will pop and open the heater circuit. The controller will still
have power. While the controller will be demanding heat from the heater, the
process temperature will fall or rise continuously until it equalizes with room
temperature. If an overheat condition occurs, let the unit cool off for one hour. If
this does not correct the problem, contact the factory.

3.5 Changing the Temperature Setpoint

The layout of the front panel is shown in Figure 3. The CL1500 incorporates a
PID digital setpoint controller. The upper display indicates the calibration block
temperature known as (PV) Process Variable, while the lower display indicates
the programmed setpoint known as (SV) Setpoint Variable. Changes to the
setpoint, units of measure and communication settings are made via the raise
and lower keys. Pressing and holding a key will cause the setpoint temperature
to advance more quickly to a desired value. Three scanning speeds are provided:
slow, medium and fast. The lower setpoint limit and upper setpoint limit are at

-23 and 257°F, respectively. While the min. and max. setting are changeable

(see “Changing the Internal Parameters,” Section 3.6), it is not advised as it may
result in damage to the calibrator.

3.6 Changing the Controller Parameter Settings

The CL1500 operates at its optimum performance when left with its factory
parameter settings. The only internal parameter that the operator should feel
the need to change is the engineering units (°C or °F) or serial communications
parameters. Figure 5 shows the menu hierarchy with factory default settings
and Figure 6 shows the programming procedure.

Operation

3.8 Testing/Calibrating Temperature Probes

Handle hot probes carefully. Use protection for your hands and the surface you will
be placing the hot probes on after removing them from the well.

When calibrating probes at different temperature points, start at the lowest

temperature and work up to the highest temperature. Do not jump up and down

from a very hot temperature to a relatively cooler temperature. This will reduce
the time it takes for the probe well to re-stabilize after you change the setpoint.
When placing probes into the well, make sure the probe tip goes all the way
down to the bottom of the probe well, the full 4.5". This will insure the degree of
highest accuracy possible when taking your reading.

After calibrating each probe, remove it from the well and place it on a protected
surface to cool. If you have another probe to calibrate, place it into the probe well
and allow the calibrator a few minutes to re-stabilize.

CAUTION:

3.9 Cooling Down Your Calibrator After Use

CAUTION:

Do not remove the power cord, main line power or turn the calibrator off until
completing the cool-down procedure.

When you have completed working with the calibrator you must cool the unit
down to ambient temperature if you intend to move your unit and/or return to
storage.
