Pushing s or t push-button select the desired input range (e.g.
AUTO)
Push the FUNC push-button.
The instrument starts measuring and the display will show:
Where:
MEAS indicates that the instrument is performing a measurement.
AUTO shows that the autoranging function is selected.
XXXXX shows the measured value.
mA is the engineering unit.
The two potentiometers allow to change the load of the instrument
under test in order to make the measuring current equal to the
desired value while the MEMOCAL 2000 is used to measure, with
high accuracy, the current in subject.
3.10.2 - RNG(L) TX simulation with read-out scaling.
The RNG(L) selection allows to associate to an input range in mA
the desired read-out range.
Example 2: it is desired to simulate a 2-wire transmitter with a
linear output range from 4 to 20 mA while the "mA measuring
device with auxiliary power supply" is programmed for a read-out
going from 0.000 to 20.000 (rpm) and it is desired to have on the
device and on the calibrator the same read-out scaling.
Pushing s or t push-button, select the RNG (L) function.
Push the FUNC push-button, the display will show the following:
By the numerical keyboard, set the desired initial scale value (For
Example 2, this value is equal to 4.000 mA).
NOTES:
1) The value assigned to "H.RANGE mA" must be higher than the
value assigned to "L.RANGE mA" parameter.
2) The value assigned to "H.RANGE EU" parameter must be
different from the value assigned to "L.RANGE EU".
When conditions 1 or 2 are not satisfied, the instrument will reject
the new value showing the "0" and it will maintain the cursor on the
rejected parameter.
3) The value assigned to "H.RANGE EU" parameter can be lower
than the value assigned to "L.RANGE EU" (reverse read-out).
Push the FUNC push-button; the cursor will go automatically on the
lower line.
By the numerical keyboard, set the desired read-out assigned to
the initial scale value (For Example 2, it is equal to 0.000 rpm).
Depress the FUNC push-button.
NOTES: For the read-out in eng. units, the number of decimal
MEAS AUTO
XXXXXX mA
L.RNG XXXXXX mA
L.RNG XXXXXX EU
