REL (Relative Readings) Modifier
When the relative modifier (REL) is selected, the reading on the primary display is
always the difference between the relative base and an input measurement. For example,
if the relative base is 15.000 V, and the present reading is 14.100 V, the display will show
-0.900.
Warning
To avoid electrical shock or damage to the meter, note that a
relative reading may not indicate the presence of dangerous
voltages at the input connectors or test leads.
Press to toggle in and out of the relative modifier. When the relative modifier is
selected: the last valid reading is stored as the relative base, the primary display zeroes
out, and "" is shown on the primary display. (The secondary display is unaffected.)
To edit the relative base, use the number editor as described in "Using the Number
Editor" later in Chapter 3).
Note
The relative modifier cannot be selected I the display shows "OL" or is
blank. (The display would be blank, for example, because of external
triggering or range changes.)
