Totalizer; 50/60 Hz Noise Rejection - bürkert 8045 Bedienungsanleitung

4.4.8 TOTALIZER

The main and daily totalizers are simultaneously reset within this menu. The reset
procedure only starts when ENTER is pressed at the "END" position in the menu.
The transmitter totally resets both totalizers when the K-factor, or the
units for flow and total are changed. The daily totalizer reset remains
available in the main menu. (§ - 4.3)
To avoid any accidental or unauthorised reset of the totalizer, set the
internal Switch2 to the locked position (section 3.4.3).

4.4.9 50/60 HZ NOISE REJECTION

This function will filter any spurious signals carried by the power supply, although
ensure that the device is not located near any large machinery as this can affect the
measurement readings. To filter the spurious signals enter the frequency of the main
power source.
FREQUENC
This function which cancels noises generated by the mains must be
properly selected even if the transmitter is connected to a DC power
supply.
