lify 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 filter out transient readings. In filter 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.

11
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 IS instruments are fitted 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 fittings.
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 IS Pressure Measurement
Instruments are not suitable for absolute pressure
measurement.
Note: Pressures in excess of maximum over range
figure with respect to atmospheric pressure, should
not be applied to either port as this could damage the
instrument or represent a safety hazard.

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.

14
4.5 Battery Replacement
Unscrew the two Allen screws at the base of the
instrument and slide off the battery cover. Replace the
battery with a 9V PP3 type as specified on the label
in the battery compartment. Replace the battery cover
taking care not to over tighten the two screws. A 2.5mm
A/F hex key is provided.
