4.7.5.1
Max/Min Display Setting
Typically, the maximum reading (Max) is displayed on the top line when the Max Hold feature is on. Sometimes it may
be beneficial to display the minimum reading (Min) on the top line instead of the maximum. The user may also display
both the maximum and minimum readings, with the maximum reading on the top line and the minimum reading on the
bottom line.
Displaying both will override the two line display configuration when Max Hold is active
(refer to
Paragraph 4.4.1).
To configure the Max Hold display setting, continue from the Max Hold mode screen or
press and hold
Max Hold
and
then press
Enter
until the following screen appears as a prompt for Max Hold display setup.

RMS Operation Relative
The relative function lets the user see small variations in larger fields. When the relative function is on, the relative
readings will appear on the top line of the display including the small delta sign (
s
) signifying the relative display. The
displayed reading is equal to the present field value minus the relative setpoint.
The relative setpoint can be configured to be the present field reading or it can be a user defined value. The relative
setpoint can be displayed on the bottom display. Refer to Paragraph 4.4.1.
To configure the relative setpoint,
press and hold
the
Relative
key for approximately 4 seconds. The relative setup
screen appears as a prompt for selecting the source of the relative setpoint.
