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 very 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.

• Keep the calibrator connected to the main power source during cool-down

period. If the power switch on the calibrator is turned to the “standby”
position
calibrator will re-activate the cooling fan. The fan will then cycle on and off
until the unit is at a safe temperature for power removal or storage.

• 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.

3.2.4 P.I.D. Indicator

When this light is pulsating, the unit is heating up the target plate.

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 Controller Parameter Settings

3.4.1 Changing Controller Parameter Settings

The parameters in your calibrator have been set and fine-tuned to provide
the best performance possible from your unit. The unit will operate at its
optimum performance when left with the factory parameter settings. The only
parameter that the operator should change is the temperature setpoint or
displayed engineering units (°F or °C). Changing any other parameter settings

will decrease the accuracy and stability of your calibrator.

3.4.2 Changing The Temperature Setpoint

The CL1000 incorporates a PID digital setpoint controller. In the default
mode the digital display indicates the probe well temperature known as (PV)
Process Variable. Holding down the modify button causes the display to show
the programmed setpoint known as (SV) Setpoint Variable. Making changes
to the setpoint or units of measurement settings are made by pressing the

(Modify) button in conjunction with the

arrow) button. Holding the (Modify) button and (Up arrow)/ (Down
arrow) button for an extended period will cause the setpoint temperature
to advance more rapidly to a desired value. The minimum and maximum
setpoints are locked out at 0 and 260°C (32 and 500°F), respectively.

(Up arrow) button or (Down

WARNING:

Do not re-program the controller’s parameter settings or change wiring inside your unit to
override the maximum setpoint value of 260 °C (500 °F). You may permanently damage your
calibrator and cause possible personal injury and/or create a fire hazard.

3.4.3 Changing The Display Units From °C to °F or (°F to °C)

Press and hold the

(Up arrow) and (Down arrow) buttons on the
controller at the same time for 3-4 seconds, then release. The display will be

3.7 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.

3.8 Cooling Down Your Calibrator After Use

CAUTION:

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.

Cool-Down Procedure:

1. Turn the calibrator to the “standby” mode (See section 3.3)

2. The cooling fan may continue to run or turn on after a several minutes if
the heater assembly inside the unit has not yet fully cooled down
to ambient temperature. Do not remove the power cord or the
main line power until the fan stops running permanently.

3. It is now safe to remove your unit from the power source and/or return to
storage.
