ATEX marking
The SDT270 ATEX version is recognizable by its specific marking located in its back plate:

ATEX classification
The SDT270A ATEX version is classified II 1 G Ex ia IIC T3/T2 Ga.

SDT Sensors for SDT270 ATEX version
The SDT270 is working with all SDT Sensors, but only the Flexible sensor ATEX and the TTS1 and TTS2 TankTest sensors can be used in hazardous areas.

Charging the battery

If you have just taken your SDT270 and this manual out of the box for the first time, please put your 270 on charge now.
The SDT270 uses an internal NiMH battery. The battery charger outlet will connect to a socket on the rear side of the 270.

When the battery is charging, the green Led of the charger flashes evenly.
The charging time will typically be 6 hours. When the green Led of the charger is continuously lit, the SDT270 battery is completely charged.
Like most batteries these days, leaving the 270 charging after the charger says it is charged does not hurt the battery – in fact it very slowly tops the charge up a little more.
You can charge the SDT270 switched off. You can also trickle charge the SDT270 switched on, so you can be using it to load and unload data, for example, and charge it at the same time.

SDT270 autonomy
A fully charged battery will give you about 8 hours of continuous use. This will vary of course depending upon your need to use the backlight and the power drain of certain external sensors that you might be using.

• You can increase the autonomy by more than 20% by disabling the LAN when your device is not connected to a network Check out the Network setting chapter to find how to disable LAN function.
• You are able also to set an Auto Power Down and a time before switching off the backlight.

Plug & unplug a sensor

The SDT270 has two measurements channels for external sensors:

• The first one is equipped with a black collar. This
  connector is meant for the black TankTest sensor (emerged sensor) It corresponds to the “TTB2” choice on the display.

• The second one is equipped with a red collar. This connector is meant for the red TankTest sensor (immersed sensor) It corresponds to the “TTR2” choice on the display.

The connections for external sensors are LEMO connectors. They are a commonly used industrial connector, considered for their reliability and their robustness. They have a sprung-loaded knurled barrel and mechanical polarisation to go only in one way round.

To plug a LEMO connector:

• Line up the red dot on the plug with the red mark on the connector.
• Insert the plug into the connector without any rotating movement.

When an external sensor is connected to the SDT270, it is automatically selected. However, you can switch between available sensors using the F1 button.
Both TankTest sensors can be connected simultaneously on the SDT270. The F1 button allows switching between both sensors.

To unplug a LEMO connector:

• Move up, towards the cable, the ring located on the bottom of the plug.
• Only pull the connector without any rotation.

 Measurement and acquisition modes

Reference mode

• In this mode the SDT270 continuously displays the measured value from the selected sensor. The value is updated four times per second.
• This mode also allows you to record the background noise of the system at atmospheric pressure during a time-lapse defined by the operator.
• The reference value is the RMS value calculated on the basis of one measurement per second during the operator defined time-lapse.
• The operator must make a separate reference value for the black sensor (emerged) and red (immersed).
• It is possible to save multiple baselines for each test and for each sensor.

The reference mode is the default mode of the device after it starts. In this mode, the device continuously displays the measured value for the selected sensor. The measured value is updated four times per second.

Recommended calibration intervals

SDT recommends annual recalibration of SDT instruments and annual verification of sensors. This periodicity is coherent with the observed long-term stability of SDT electronic equipment’s.
However

• For new equipment leaving the factory the initial period is extended to 15 months instead of 12 (to avoid any possible discrimination between users due to transportation time, customs clearance, etc.)

• SDT recognizes that each customer may have their own Quality Assurance Standards and internal requirements. If a customer has established a Quality Assurance Program that includes a documented procedure for measurement deviations,
  and if an instrument and the relevant sensor show acceptable deviations and do not show signs of physical damage, then calibration periodicity could be extended to two years.

• Third party organizations having more authority (Class, or State Administrations) may have defined their own regulations for example 6 months, or 2 years calibration interval: by evidence, local legally applicable regulations supersede SDT rules.

For these reasons, SDT Calibration Certificates do no more mention a “calibration due date”, but simply the “last calibration date”.
For user convenience, the date of the last calibration of an SDT200 or 270 instruments
can also be found in the menu screens.
