PCL240

1. Introduction

The PCL240 is designed to be an accurate, easy to use pressure
calibrator/manometer for a variety of pressure measuring applications. Its
two port differential design allows the unit to be used in both gage and
differential measure-ments providing a high degree of versatility. The
PCL240 is capable of storing maximum and minimum pressure readings
along with a hold function to freeze a reading if desired.

1.2 Unpacking

Remove the packing list and verify that all equipment has been received. If
there are any questions about the shipment please call Omega at 1-800­826-6342. When the shipment is received 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 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.

The following definitions apply to the terms “Warning” and “Caution”.

• “Warning” identifies conditions and actions that may pose hazards to the
user.

• “Caution” identifies conditions and actions that may damage the
instrument being used.

Use the calibrator only as specified in this manual, otherwise injury and
damage to the calibrator may occur.

3

Warning

To avoid possible electric shock or

personal injury:

• Do not apply more than the rated voltage. See specifications for
supported ranges.

• Follow all equipment safety procedures.

• Do not use the calibrator if it is damaged. Before you use the calibrator,
inspect the case. Look for cracks or missing plastic. Pay particular
attention to the insulation surrounding the connectors.

• Select the proper function and range for your measurement.

• Make sure the battery cover is closed and latched before you operate the
calibrator.

• Remove test leads from the calibrator before you open the battery door.

• Inspect the test leads for damaged insulation or exposed metal.

• When using the probes, keep your fingers away from the probe contacts.
Keep your
fingers behind the finger guards on the test leads.

• Do not use the calibrator if it operates abnormally. Protection may be
impaired. When in doubt, have the calibrator serviced.

• Do not operate the calibrator around explosive gas, vapor, or dust.

• Disconnect test leads before changing to another measure or source
function.

• When servicing the calibrator, use only specified replacement parts.

• To avoid false readings, which could lead to possible electric shock or
personal injury, replace the battery as soon as the battery indicator
appears.

Caution

To avoid possible damage to calibrator or to equipment under

test:

• Use the proper jacks, function, and range for your measurement or
sourcing application.

2. Getting Started

Before beginning, become familiar with the keypad layout and the
configuration of the pressure manifold connections. Note the location of
the high and low pressure ports as indicated by the label on the rear of the
calibrator.

Install the 9V alkaline battery by removing the two retaining screws
securing the battery compartment door. Once the battery is in place secure
the battery compartment door by tightening the retaining screws. The
PCL240 is now ready for operation.

3. Media Compatibility

The PCL240 low pressure models (10”, 200”, 30 PSI and 100 PSI) can
work with liquids and gases that are compatible with the following wetted
materials:

• Silicon

• RTV

• Glass

• Ceramic

• Buna-N

The high pressure versions of the PCL240 (300 PSI, 3,000 PSI) can work
with any liquid or gas compatible with 316 stainless steel and nickel plated
brass.

4. Operating Procedure

1. Connect the desired 1/8NPT fitting to the pressure manifold. Note that

for gage (positive pressure) measurements use the HIGH input port. If
differential measurements are being made, both ports must be used with
the higher of the two pressures going into the HIGH input port. The 300
and 3000 PSI versions have a single port since they operate as a gauge
only device.

2. Turn on power and select the desired Engineering units you wish to use.

Pressing the ENG. UNITS key will allow you to toggle through the
available selections.

3. With the calibrator open to ambient pressure press the ZERO key to

zero the reading.

4. Apply the pressure to be measured. If the reading is unstable due to

pressure fluctuations, press the DAMP key to dampen the reading. To
disable the damping function, press DAMP again.

5. The PCL240 can be used to monitor a pressure then recall the maximum

and minimum values. When pressure is introduced into the port, the
pressure value is automatically stored as maximum or minimum values.
As the pressure changes, the minimum and maximum values are
constantly updated. These stored values can be cleared at any time by

5

pressing the CLEAR key. The memory is also cleared when the
calibrator is turned off.

To recall a stored value, press and hold either the MAX or MIN key,
depending on the reading you wish to review. When the key is released
the calibrator returns to the present reading value.

6. The PCL240 can be used to hold a pressure reading to be viewed after

the pressure has changed. Pressing the HOLD key enables the hold
function, pressing HOLD again disables it.

5. Accuracy

The PCL240 is checked against a NIST traceable reference before
shipment to verify that it meets its accuracy specification. This accuracy is
based at 25°C and error allowances must be made when operating at
extreme temperatures. The specifications below list the stability and
operating temperature range of the PCL240.

7. Maintenance

A. Battery Selection

The PCL240 operates on a standard 9V alkaline battery or an optional
rechargeable 9V Ni-Cd battery. For most applications the 9V alkaline
battery will suffice; however, in heavy use applications the 9V Ni-Cd may
be a better choice. The 9V Ni-Cd battery supplied by Omega will offer
approximately 3 hours of continuous use at 12 mA output on a full charge
(the alkaline battery will yield about 12 hours). The charger supplied by
Omega will provide an overnight charge rate (10-12 hours) and will also
power the PCL120 for bench use while maintaining a float charge on the
Ni-Cd battery.

Warning: Never connect the AC adapter/ charger with the 9V alkaline
battery installed.

To order the 9V Ni-Cd battery or AC adapter/charger contact Omega
Engineering at 800-826-6342.

B. Input Protection

The PCL240 incorporates a fuseless input protection and will tolerate most
misconnections up to 250 VAC or 250 VDC for up to 30 seconds duration.
Because of this protection no maintenance is required.

C. Calibration

The PCL240 is designed to hold its rated accuracy for a minimum of one
(1) year. It is therefore recommend that an annual re-calibration be done
to ensure operation within specification. Contact Omega’s Customer
Service Department for re-calibration information at 1-800-826-6342 or
www.omega.com.
