Shopaemc .Ca 1.877.766.5412 - AEMC 6470 User Manual

is found by the instrument, the blinking NOISE symbol appears together with the
measurement results.
In the MANUAL mode, the blinking NOISE symbol appears after the measurement
has been started or if the measurement frequency is too close to the detected dis-
turbance frequency. The user may now choose another frequency that is out of the
previously measured disturbance spectrum. If the new measurement frequency
provides a disturbance free measurement, the NOISE symbol disappears.
The external voltages are not shown on the display during the measurement (State
2) but only before a measurement starts (State 1) and after the measurement ends
(State 3), unless the DISPLAY button is pushed during the measurement.
In State 1 there is no NOISE recognition.
Pushing the START/STOP button sets the measurement into action and switches
the display to the initial screen, depending on the function. The main procedure is
as follows:
• U disturbance check before the functional measurement. No measurement
if the measured voltage U
• Connection check.
• A long press (>2s) on the
electrodes resistances.
• Start of the functional measurement.
STOP is only active in MANUAL mode and when the measurement is running. If no
main measurement result has occurred and the START/STOP button is pressed,
the instrument returns to the initial screen and State 1.
The Model 6470 can be operated via the USB interface (complete remote mode)
in all measurement functions except the SET-UP position. In the SET-UP position
there is no interface communication allowed.
