Special functions:
DC/AC: Allows to choose between static field
DC (0 Hz), variable AC (without the static
component) or DC + AC (static and variable).
To be able to measure the static fields very
precisely, you have to use the DC mode. This
also allows not to take into account the noise
or signals that may exist above 1 Hz.
Zero: this function allows to make the
zeroing of the hall sensor integrated in
the probe. It is very important to do this
operation before making an accurate
measurement or to correct a deviation in
temperature. How to proceed:
• Turn on the equipment with the probe
connected and get into the desired mode
(DC, AC or DC+AC).
• Wait 2 minutes (even more if the equipment
was at a temperature different from the place of measurement).
• Position the tip of the probe in the Zero Gauss chamber.
• Press the “Zero” button in the SMP2 menu.
• Repeat these last 2 operations each time you want to compensate for any
change in temperature.
