2.2.0 TESTS
2.2.1 SET OUTPUT This sets the current output to a test value
[mA]. The output will change to the given
value, independent of the measured value.
The current output will go back to the
measured value when the display goes back
to the menu level.
3.5, 4, 6, 8, 10, 12, 14, 16,
18, 20 or 22 mA
3.5 mA
2.2.2 DIAGNOSTIC This starts the hardware test. Push [>
>>
>] many
times to show:
• D1, the time of operation
• T1, temperature of the electronic
converter board
• I1, loop current (internally measured
value)
• I2, load current (NOTE: this data is not
available at this time)
• V1, voltage 5.6 V. If the voltage is not
5.0<V1<5.7, speak to the supplier.
• V2, voltage on capacitors. If the voltage is
not 3.2<V2<3.4, speak to the supplier.
• V3, voltage 3.3 V. If the voltage is not
3.2<V3<3.4, speak to the supplier.
• C1, reset counter (watchdog timer). If
C1>1, replace the signal converter.
If an NE 107 symbol and a status marker are
shown, refer to
Device status (markers) on
page 76.
If you push [>
>>
>] again, the display goes back
to the menu level.
2.2.3. The corrected spectrum. TBD.
2.3.0 BASIC PARAM.
2.3.1 TANK HEIGHT The distance from the flange face / thread
stop of the tank connection down to the tank
bottom. If the tank has a dish-shaped or
conical bottom, the tank height is measured
to a point on the tank bottom directly below
the antenna. For more data about level
measurement, refer to Level measurement
on page 72. For more data about distance
measurement, refer to Distance
measurement on page 71.
