How to Use the Meter
15
For increased sensitivity, the analog pointer moves
across the scale four times for each range. The
pointer returns to 0 (wraps around) when the
equivalent digital display reaches 1024, 2048, and
3072 counts. Select the next higher range if the
pointer is too sensitive.
The analog pointer indicates a value lower than the
digital display (up to 2.5% of range). Examples on
the 40V range are:
Digital Display = 5.00V 15.00V 25.00V 35.00V
Analog Pointer= 4.8 4.5 4.5 4.2
Wrap = First Second Third Fourth
Indication = 4.8V 14.5V 24.5V 34.2V
With stable inputs, use the digital display for the best
sensitivity and precision.

Analog Display Scale
Scale for each 1000 counts in the digital display.
Q ± Analog Display Polarity
Indicates the polarity of the input except in the
Frequency Counter mode, when it indicates the
polarity of the trigger slope (edge).
R 4000 Input Range Annunciator
mV
Displays 4, 40, 400, or 4,000 input range for volts,
amps, or ohms, and 400 mV.
S OL Overload Indication
Displayed on digital display when input (or math
calculation in REL mode) is too large to display. If you
are taking duty cycle readings, OL is displayed if the
input signal stays high or low. All segments are
illuminated on analog display.
Items 20-23 describe annunciators that indicate the mode
or state in which the meter is operating:
T AUTO Autorange
Meter is in the autorange mode and will automatically
select the range with the best resolution. Meter
powers-on in autorange mode.
In the autorange mode, the meter ranges up at 4096
counts and ranges down at 360. When the meter is in
the Manual Range mode, the overrange arrow is
displayed until you manually select a range
appropriate for the input value.
See item 9 for manual ranging.
