2.Operating Instructions
2.1 Set up
Place the unit on a stable table.
•Open the 4 (four) locks and take the lid of the case.
•Check the calibrator for damages.
•Plug the power supply cable in the right side of the unit.
•Control the power supply indication before plug in.
2.2 Operating Instructions
The TRAQC-8 is a pressure calibrator with a maximum of 200 bar and is design for a so-called
"dead end" system. The calibrator includes a high pressure reducer which has to be fed by an
external pressure source of maximal 200 bar or by the internal gas bottles. Depending on the
range of the pressure sensor which is mentioned on the front side of the TRAQC-8, the range of
the reducer is selected. On the pressure outlet of the reducer are a pressure shut off valve and
a bleed valve for fine adjustment of the test pressure.
•Close the “bottle shut off valve” by turning it fully clockwise.
•Decrease the “reducer” by turning it fully counterclockwise.
•Close the “pressure shut off valve” by turning it fully clockwise.
•Open the “bleed valve” by turning it fully counterclockwise.
•Connect the “test” coupling to the unit to be calibrated.
•Close the “bleed valve” and open both the “pressure shut off valve” and “bottle shut off
valve”.
•Slowly increase the pressure with the “reducer” until the maximum admissible pressure
for the unit under test is reached.
•Close the “pressure shut off valve”, close the “bottle shut off valve” and decrease the
“reducer” to minimum.
•Check with the TRAQC-8 if there is any leakage; this becomes apparent by an extreme
change of the test pressure.
•Remove the pressure from the system by opening the “bleed valve”(1).
•Eliminate any leaks and repeat the test as described above until all leaks are eliminated.
•Close the “bleed valve”.
•Open both the “bottle shut off valve” and “pressure shut off valve”.
•Increase the “reducer” to circa 110% of the desired test pressure. Than close the
“pressure shut off valve”.
•For regulating the test pressure:
-Slowly opening and closing the “pressure shut off valve” will result in a pressure
increase.
-Slowly opening and closing the “bleed valve” will result in a pressure decrease.
•A measurement can be performed when the “bottle shut of valve”, “pressure shut off
valve”, the “bleed valve” are all closed.
•Repeat the procedure as often as a new test pressure is desired. When all test pressures
have been generated repeat the following sequence for getting the system back to
atmospheric pressure:
-Close the “bottle shut off valve”
-Open the “bleed valve”
-Decrease the “reducer” to the minimum.
-Open the “pressure shut off valve”.
-Disconnect the test hoses
The valves have a soft seat and a tight shut-off. It is not necessary to close them with
excess force.

2.2.1 Measurement of external test pressures
It is also possible to measure pressures generated by external systems. In this case the reducer
and the gas bottle will not be used. All control valves will have to be closed.
2.3 Instructions for the refilling of the gas bottles
The refilling of the gas bottles can be done by using either another bottle or a high pressure
compressor. The maximal refilling pressure is 200 and the capacity is 2 liters.
When the refilling is done from another bottle, the included RU 3 connector can be used.
The refilling by a high pressure compressor can be made by a direct connection.
•Close both the “bottle shut off valve” and the “pressure shut off valve”.
•Increase the “reducer” to a the maximum.
•Open the “bleed valve”.
•Connect the filling hose to the ‘refill connection’.
•Set the compressor or the external bottle to a maximum of 200 bar.
•Slowly open the “bottle shut off valve”. The gas bottle will be refilled and the
pressure of the bottle can be checked on the manometer.
•Slowly let the gas bottle be refilled. A quick refilling will increase the temperature.
An increase in temperature will affect the pressure by increasing it. This means no
optimal filling will be obtained.
•Close the gas ‘bottle shut off valve” and shut-off the compressor.
•To get the filling hose free of pressure, decrease the “reducer” to a minimum and
open the ‘Pressure shut off valve’
•Then disconnect the filling hose.
2.4 End of use
•Close the “bottle shut off valve”
•Open the “bleed valve”.
•Set the “reducer” to a minimum.
•Open the “pressure shut of valve”.
•Disconnect the unit under test from the unit.
•Disconnect the test hoses and put them in the carrying case in the lid of the 8185.
•Place the cover of the TRAQC-8 back on and close the four locks.
2.5 Storage
End the utilization of the TRAQC-8 as follows:
•Store it indoors, in a temperature between 0 and 60° Celsius.
•Decrease the “reducer” turning it fully anti clock wise
•Open both the “bleed valve” and the “pressure shut off valve”.
•Empty the internal gas bottles by slowly opening the “bottle shut off valve”.
•Place the cover of the 8185 back on and close the four locks.
•Place the case a horizontal position.
Equipment which has rechargeable batteries will need to be stored with fully charged batteries,
charging and discharging of batteries one every 3 months is advised.
When connected to the mains power a trickle charge will be maintained.

TRAQC-8 04/2017 EN Rev.4 page : 13
2.6 Power Supply
The unit is equipped with an internal not removable Li-Ion battery. The charging of the batteries
is fully automated. The TRAQC-8 is charged when its connected to the mains power supply
charging will start as soon as the instrument is connected to the mains supply.
The instrument can be used while charging the battery, but the required charging time could be
increased depending upon the selected operating mode of the instrument.
2.6.1 Battery status display
The status of the battery is displayed with a battery symbol on the lcd display when the
instrument is switched on.
During charging the battery symbol will be filled with lines until it is completely filled and when
all lines are drawn the symbol will be cleared and starts filling again.
When charging is completed the symbol will be completely filled and remains filled as long as
the instrument is connected to the mains supply.
2.6.2 Operating time indication
The instrument has an internal ‘gas gauge’ to measure the battery capacity, this gas gauge is
automatically updated when the battery is charged or discharged and is used to indicate the
battery charging state and remaining operating time.
The charging state of the battery is indicated with lines in the battery symbol.
When the battery is full all lines in the battery are drawn and when the instrument is operating
on the battery less lines will be shown.
The number of lines shown in the battery is a rough indication of the remaining battery
capacity.
When the remaining operating time drops below 3 hours the remaining time will be shown next
to the battery symbol
The operating time of the instrument on the indicated charge state depends upon the
usage of the instrument, Operating modes where the electrical outputs are used draw
more current from the battery and therefore shorten the operating time more than other
modes.
2.6.3 Instrument charging before storage
The instrument should not be stored for longer periods with an empty battery, doing so will
reduce the capacity of the battery and shorten the battery life.
When the instrument must be stored the battery should be charged to at least 50% of its
indicated capacity.
2.6.4 Battery Replacement
The battery can only be replaced by Tradinco or a Tradinco approved repair facility.

3.User Configuration
3.1 Pressure Setup
The “Pressure Setup” menu shows the options for pressure inputs.
After pressing the ‘MENU’ key (F1), press the ‘ARROW’ keys until
the “pressure setup” is selected, then press ‘ENTER’ key (F1). The
available pressure options for the instrument are now displayed
(see figure) and it is now possible to select one of options with the
‘ARROW’ keys. The different options of the pressure setup are
described in the following paragraphs.
3.1.1 Pressure range
This menu option is available in instruments with 2 or more
pressure sensors installed.
When you select this option a menu with the available pressure
ranges is shown,
You can select a line with the arrow keys and then switch the
selected pressure range on or off depending upon its current status
when the electrical ranges are not active, otherwise you can select
only one range to be displayed. See also section 2.11.
3.1.2 Pressure unit
The menu to select the pressure unit can in most operating modes be accessed by pressing the
‘UNIT’ function key, There are however operating modes where this is not possible , for these
modes the pressure unit selection is also available in the pressure setup menu, see section 2.10.
3.1.3 Averaging on/off
A progressing averaging can be applied. The reading speed is standard three times per second.
The objective is to display the fluctuating measuring signals in a reliable manner. If averaging is
switched on, this is shown by ‘𝑥’ above the pressure unit reading in the ‘measuring mode’ menu.
To enable or disable the averaging function select the “averaging on/off” option in the “pressure
setup” menu.
The default state is the “averaging off”. To change the current state press ‘ENTER’ key (F1).
3.1.4 Averaging setup
The number of times that averaging must be performed can be set
as follows: Select the “averaging setup” in the pressure setup
menu with the ‘ARROW’ keys and press ‘ENTER’ key (F1) to
confirm. Now use the ‘ARROW’ keys to change the number of cycles
to the desired one, press ‘ENTER’ key (F1) to confirm.
The number of cycles default is 6. The cycles can be set from 3 to
9.

3.1.5 Resolution Setup
To change the number of digits (from 3 to 6) select “resolution
setup” in the “pressure setup” menu and use the ‘ARROW’ keys to
change the number of digits, confirm by pressing the ‘ENTER’ key
(F1)
3.1.6 Conversion Table
The pressure indicator is capable of displaying
pressure according to the SI or the ANSI
standards. Change between SI and ANSI using
the ‘ARROW’ keys and confirm by pressing
‘ENTER’ key (F1).
The ANSI standard has other conversion
factors than the SI standard; see the following
table for a number of units:
3.1.7 Set customer unit
The density of seawater for the region where the pressure
indicator is used can be set here.
When a test pressure is set, the TRAQC-8 can calculate the
pressure into meters under water. The density of the seawater
will differ in different parts of the world and the value has to be
adjusted for correcting for the pressure under water.
The seawater density is set in kg/m3and can be adjusted from
950 up to and 1100 kg/m3.
For adjusting the unit, use the left and right arrow keys to select
the digit which has to be altered and use the up and down arrow
keys for adjusting the selected digit. When the right value has
been set, press the enter key (F1).

3.1.8 Absolute mode
This option is available when the instrument has two or more
pressure ranges and the last range is an absolute range or
barometric reference sensor.
In instruments with only one gauge range and an absolute range
you can switch the absolute mode on or off, in instruments with
two gauge sensors and a absolute sensor you can select the
range that should be displayed in absolute mode.
Note : In absolute mode the measured value of the absolute
range is added to the measured value of the gauge range. This
means that the uncertainty of the measurement is increased.
When the absolute mode is active the measured barometric
pressure will be displayed on the line just above the descriptions
of the function keys
This pressure is always displayed in mbar.
3.2 Electrical Input A Setup
The electrical connections can be used to measure currents
between 0 - 24 mA, DC voltages between 0 to 11V, resistance of 0
–4000 ohm, temperature with an RTD probe and for connection of
a switch.
To access the menu options for the electrical input first press the
‘MENU’ key, then select the ‘electric setup' line with the ’ARROW’
keys and press the ‘ENTER’ key, will be displayed. The options are
explained in the next paragraphs.
This menu has more than 8 entries, when you step through the
menu with the ‘UP’ and ‘DOWN’ arrow keys the menu scrolls to show
the additional items.
The options are explained in the next paragraphs.
