8.7 MAG 6000 SV
Excitation frequency
The MAG 6000 SV excitation frequency can be changed in sensor characteristics menu
(Page 84) to one of the following frequencies:
●
1
9
/
16
Hz
● 3
1
/
8
Hz
● 6 ¼ Hz
● 12½ Hz
● 25 Hz
● 44 Hz
Note
Calibration has been made with the frequency stored in SENSORPROM
®
memory unit. A
change in excitation frequency is not recommended and will always mean decreased
measuring accuracy. In some instances, however, it may be necessary to change
frequency due to pulsating flow from piston pumps or other resonance frequencies from
surroundings.
It is highly recommended to carry out a zero point adjustment after changing the excitation
frequency as the offset is affected by the frequency selected. When this is done, the
decrease in measuring accuracy can be kept below 1% o.r.
A too high frequency for the sensor used will cause a coil current alarm indication.
