Selecting a Measurement Rate
Selecting a Measurement Function
In autoranging mode, the Meter automatically selects the next higher range when a
reading is greater than full-scale. If no higher range is available, 0L is displayed on the
primary or secondary display to indicate an overload. The Meter automatically selects a
lower range when a reading is less than 95 % of full-scale of the lower range.
In autoranging mode, pressing U or V changes the mode to manual ranging. If U
is pressed, the next higher range is selected (if there is one). If V is pressed, the next
lower range is selected.
In manual ranging mode, the range that is set when you enter the mode becomes the
selected range. The Meter remains in the selected range regardless of input. Manual
ranging can only be performed on readings shown on the primary display. The secondary
display is in autorange or when the primary and secondary displays are set to the same
function, the secondary display uses the same range as the primary display.
The Meter takes measurements at one of three user-selected rates: slow, medium, and
fast. Rate selection allows you to maximize measurement speed, which can affect
accuracy. The rate selected is shown in the primary display as Slow, Medium, or Fast.
Press J to step through the measurement rates. The rate selected applies to all basic
measurements except frequency. When frequency is measured, the rate is fixed at
4 measurements per second. The measurement rate is always fast for Diode and
Continuity test. Pressing J does not affect the frequency update rate.
To select a measurement function, press the applicable function button (See Table 3-1).
The applicable annunciator is displayed to indicate the selected function. (For example, to
measure dc voltage, press D. DC is displayed.)
To select ac + dc total rms readings, simultaneously press A and D for more than
two seconds; or simultaneously press B and E for more than two seconds.
If a reading is shown on the secondary display when a function button is pressed, the
secondary display turns off and that function is selected for the primary display.
