CALIBRATION, CERTIFICATION AND SERVICE

Certication

Comark can provide certicates of calibration for its whole product range, to suit

ISO 9000 and other quality assurance procedures, food hygiene regulations,

HACCPs and environmental regulations. Comark certicates are produced by

independent quality controlled processes which compare product performance
against agreed National Standards. For peace of mind and best practice Comark

recommend annual certication/recalibration.

Two levels of certication are available for infra-red temperature and non
temperature instruments, excluding humidity:- UKAS certicates via an external
accredited laboratory and NPL traceable certicates from the Comark calibration

laboratory.

Three levels of certication are available for contact temperature products and

these are detailed here:

a) UKAS Temperature Certication

The Comark UKAS (United Kingdom Accreditation Service) accredited

temperature calibration laboratory is one of the nest in the UK. Comark
UKAS certicates can offer the lowest uncertainty of 0.01°C and

provide independent proof of correct calibration using equipment and

2. KEY FUNCTIONS

2.1 ON/OFF Key

Press once to switch on the instrument. Repeat to
switch off.

Holding down the key when switching on will display the
maximum pressure range of the instrument in PSI.

Holding down the key when switching off will display all
segments as a test.

2.2 ZERO Key

Press to zero the current readings on the display
to nullify any offsets caused by large temperature
variations. The instrument will retain the zero value in
memory even after switch off, so that the zero reading
will be displayed when the instrument is switched on
again. The zero key can be used whenever offsets
occur. Please note that pressing the zero key has no
effect whilst the instrument is in hold or record modes.

2.3 SCALE Key

Press to display the pressure measurement in each of
the different scales available. The selected scale unit
is retained in memory even after switch off, so that the
selected unit can be displayed when the instrument is
switched on again.

2.4 HOLD Key

Press to hold the displayed reading and press again to
resume measurement. The scale key will operate while
the instrument is in hold mode so that the held reading
can be displayed in different scales.

2.5 FILTER Key

Press to lter out transient readings. In lter mode the

instrument will average the readings taken over the
last 4 seconds (16 readings) to provide a more stable
reading on the display. Press the key again to resume
normal measurement.

9

2.6 RECORD Key

Press once to put the instrument into record mode. This
will be indicated by the word RECORD on the display.
Maximum and minimum pressure readings can be
stored and displayed while the instrument is in record
mode. When the instrument is in record mode, press
key once to display the current maximum reading and
press again to display the current minimum reading.
Pressing the key a third time will return the display to
normal measurement.

Record mode can be cancelled and the max/min
readings cleared by pressing and holding down the key
until the word RECORD disappears from the display.

The scale key will operate while the instrument is in
record mode so that the max/min readings can be
displayed in different scales.

2.7 AUTO Switch Off

The instrument can be programmed to auto switch off
by pressing and holding down the HOLD key while
using the ON/OFF key to switch on the instrument.
The word AUTO appears on the display to indicate
auto switch off mode and the instrument will switch
itself off approximately 3 minutes after the last use of
the keypad. Auto switch off mode can be cancelled
by pressing and holding down the HOLD key while
switching on manually with the ON/OFF key.

3. CONNECTION TO PRESSURE SOURCES

The C9500 Series instruments are tted with

1

/8" BSP female connectors. The following checks
must be made before connecting the instrument to
a pressure source:-

Check the security of all ttings.

Check that the pressure source does not exceed the
ratings for the instrument as set out in Table 1.

Check that the gases to be measured will not damage
or corrode stainless steel, brass, glass, ceramic, silicon,
nickel, aluminium, gold or epoxy resin.

Note: Comark C9500 Series Pressure Measurement
Instruments are not suitable for absolute pressure
measurement.

Note: Pressures in excess of maximum over range

gure with respect to atmospheric pressure, should

not be applied to either port as this could damage the
instrument or represent a safety hazard.

TABLE 1

Instrument Pressure Range Maximum Over/
Under Pressure

C9551 0 to ±2 PSI/140mbar 6 PSI/400mbar
C9553 0 to ±5 PSI/350mbar 15 PSI/1000mbar
C9555 0 to ±30 PSI/2000mbar 90 PSI/6200mbar
C9557 0 to ±100 PSI/6900mbar 200 PSI/13700mbar

4. OTHER FUNCTIONS

4.1 Battery Low

Low battery is indicated by the symbol BAT on the
display. Replace the battery as soon as possible after
this symbol appears.

4.2 Over Range Pressure

If the pressure measured (either positive or negative
pressure) exceeds the full scale of the instrument, the
display will show – – – –

If this occurs the pressure must be reduced to avoid
damage to the sensor in the instrument.

4.3 Over 9999 Reading Indication

If the numeric value for display exceeds ±9999, with
or without a decimal point, the display will blink and
suppress the top (5th) digit, whilst continuing with
correct values of the lower 4 digits.

4.4 Differential or Gauge Measurement

C9500 series instruments can be used in either a gauge
or differential pressure measurement system.

Gauge:

For positive gauge measurements the negative
(-ve) port should be left open to atmospheric pressure
and the positive (+ve) port used to input the pressure.
For negative gauge measurements the positive (+ve)
port should be left open and the ‘vacuum’ applied to
the negative (-ve) port. Please note that in this case
the reading displayed will be positive even though a
vacuum is being measured.

Differential:

When measuring differential pressures, ensure that the
most positive (+ve) pressure is applied to the positive
(+ve) port.

12

4.5 Battery Replacement

Unscrew the two screws at the base of the instrument
and slide off the battery cover. Replace the battery with
a 9V PP3 type battery. Replace the battery cover taking
care not to over tighten the two screws.

4.6 Use with Pressure Test Kit

The C9500 series instruments can be used together
with the optional TK2 pressure test kit as a low cost
calibration system for checking or calibrating other
pressure instruments.

To use TK2 as a calibrator, connect a calibrated C9500
series instrument, suitable for the maximum pressure
to be used, to one of the ports on the hand-pump.
Connect the instrument to be checked or calibrated to
the other port. Read the instructions supplied with the
TK2 kit for details of the pump operation. Ensure the
C9500 meter is zeroed with the pressure relief valve
open before measurements or adjustments are made.

Note: With the C9551 meter it is possible to over­range the instrument with just one squeeze of the
pump handle. If this should occur unscrew the pressure
release valve slowly until the display again shows a
pressure reading then tighten. The volume adjustment

on the pump may now be used for ne control of the

applied pressure.

4.7 Silicone Version

Although C9500 instruments are generally used for gas/
air measurement, special versions are available with
silicone protection to allow liquid pressure measurement
without sensor corrosion.
