The use of the separate ranges below and above the internal measuring range
switch at 600 A/cm only makes sense with the analogue output probe P-T4A.
If you are using a non-analogue probe with firmware below version 8.2 (before July
2018), this feature is not available. You will receive the message
Probe not
adequate .
For the P-T4A probe, values from both areas within a measurement series would
lead to a wrong representation. If DC Low Range is selected and the range limit is
exceeded, the display values are cut off.
The display shows the symbol DC-Lo or DC-Hi behind the current measured value.

Switch to the AC-RMS Auto Range in order to measure alternating fields.
The AC symbol is shown behind the current measured value on the display.
In the case of sinusoidal AC fields, the respective effective value (true RMS) is displayed.
The respective conversion factors for full-wave and half-wave rectification are given
in the DIN standard 54 131 Part 1.

Switch to the Peak Low Range , in former firmware versions known as P1 range, in
order to measure peak fields less than 600 A/cm (750 Gauss, 75 mT) . The
Peak Lo symbol is shown behind the current measured value on the display. If the
measurement range is exceeded the display shows - - - - .
Switch to the Peak High Range , in former firmware versions known as P2 range,
in order to measure peak fields of more than 400 A/cm (500 Gauss, 50 mT). The
Peak Hi symbol is shown behind the current measured value on the display. (PEAK
P2 symbol is shown). If no peak value is displayed in the Peak Hi mode, this means
that the peak value is less 400 A/cm. In this case select the Peak Low Range.
If there is already a measured value in the peak value memory and a higher
measured value is recorded then the old measured value will be overwritten by the
new one. A short acoustic signal is sounded when the measured value is exceeded.
The peak value memory is reset via the -0- key.
When measuring AC fields in peak value memory mode the peak value and not the
effective value will be saved if the AC field is sinusoidal.
