POWER SUPPLY
The T214 manometer is designed for portable operation using the supplied
internal battery. This is supplied fully charged but, if the instrument's display
screen does not light up or the LOW BATT message is displayed at switch on,
the battery-charging instructions given on page 11 should be followed.
PORTABLE OPERATION
The T214 manometer is designed for continuous portable operation during
twenty hours.
The instrument uses a NiMH type battery. One of its characteristics is the
reduction of the memory effect with respect to NiCd batteries. This effect
involves a reduction in the battery's recharging capacity. To maintain this
recharging capacity, it is recommended that full recharging and discharging
cycles be carried out. However, although long, its lifetime is limited and in time
will have to be replaced by a new one.

OPERATION AS MILLI-AMMETER
The following instruction should be followed when using the T214 for current
readings in the 0-30 mA range, normally to verify the response of a 4-20 mA
pressure transmitter
WARNING: The T214 does not include an internal 24 Vdc power supply and
must be externally powered.
1.- Use the key on the instrument's front panel to select the
current reading mode, which is indicated by the display of the mA icon
on the screen.
2.- The necessary connections should be made using the cables supplied on
the side of the T214 respecting the polarity indicated on the front panel.
3.- The instrument is now ready to take current readings in the range -30 / 0 /
+30 mA.

MANOMETER-MILLI-AMMETER ALTERNATIVE OPERATION
Once the T214 is ready for operation in accordance with the section seen on
this and the previous pages, it can be employed for combined reading of
pressure or current by simply using the key on the front panel.
This possibility is specially helpful with pressure and current transmitters.
When the mA icon is visible, the displayed readings are current values. When
this indicator is not visible, the displayed readings are pressure values.
NOTE: The T214 instrument includes current input protection against current
peaks and voltages up to 30 V.

CHANGING ENGINEERING UNITS
The T214 manometer provides the possibility to perform pressure readings in
ten different engineering units.
These units are selected as follows:
1.- Press and maintain the key on the front panel until the desired unit
is displayed.
2.- Release the key when the desired engineering unit is displayed.
3.- Verify the selected unit by briefly pressing the key.
The available units are then displayed on the T214 screen, together with their
corresponding equivalence.
NOTE: The key has two functions:
1.- Pressing it once will display the current unit.
2.- Maintaining it pressed for more than one second will cause the unit to
change, with all those available being displayed consecutively.

INSTALLATION AND USE
The T214 manometer incorporates a folding support at the rear of the box that
permits the instrument to be used in an upright position, which facilitates both
use and reading.
It is recommended that the instrument be returned to its protective case when
not in use. It is also recommended that the battery be removed when the
instrument is not going to be used during a prolonged period of time.
ADJUSTMENTS
The T214 manometer leaves the factory fully adjusted and no further
adjustment is required. However, it is recommended that it be recalibrated
approximately once a year, with any necessary adjustment being carried out.
In order to correctly adjust the unit, it should be confirmed that all necessary
elements are available, such as adequately precise standards and required
means of connection.
In order to determine that the standards are adequate, consult the instrument's
technical sheet and check that the standard to be employed meets the ration
requirements, which must be greater than 2 to guarantee the correct assigned
uncertainty.
Note that a wrong choice of standard could lead to incorrect unit specifications.
If suitable standards are not available for calibration and adjustment, it should
be sent to an accredited laboratory in order to obtain a correct level of
certification and traceability.
Input current adjustment
1.- Connect the instrument's measuring terminals to a current generator set
to 20 mA.
2.- Adjust with potentiometer P1 (located in the exterior section of the battery
compartment identified as I).

Input pressure adjustment
1.- Perform the zero adjustment for the pressure measurement by pressing
the corresponding key indicated as *.
2.- Apply the maximum range pressure to the equipment.
3.- This is adjusted using potentiometer P2 (located in the central part of the
battery compartment).
*Non-functional key in case of absolute pressure. In this case, zero must be set using the
potentiometer located in the battery compartment and identified as Z and applying the lowest
possible absolute pressure.
NOTE:
The battery must be removed in order to access the adjustments in its .
compartment. In this situation the T214 must be powered using the charger/
power supply PS 30 B.
