2 Features and Functions
Configuring AC Voltage and Current Measurements
For ac voltage and current measurements, your configuration menu
choices are:
AC FILTER , RANGE , NULL and NULL VALUE .
• AC FILTER : Allows you to select one of three choices ( SLOW , MEDIUM or
FAST ) of bandwidth (ac signal filter), enabling you to optimize
low–frequency accuracy or achieve faster ac settling times.
•
RANGE
: Allows you to let the multimeter automatically select the range
using the autoranging feature (select
AUTO
), or you may select a fixed
range using manual ranging (select
MANUAL
).
• NULL : Allows you to enable (select ON ) or disable (select OFF ) the null
measurement feature, which measures the difference between a stored
null value and the input signal.
•
NULL VALUE
: Allows you to view and edit the null value.
Configuring Resistance Measurements
For 2–wire and 4–wire resistance measurements, your configuration menu
choices are:
INTEGRATION , RANGE , OFFSET COMP , AUTO ZERO , NULL and NULL VALUE .
• INTEGRATION : Allows you to set the integration time for the measurement
in two ways; in power–line cycles (select NPLC ) or in seconds (select
APERTURE ).
•
RANGE
: Allows you to let the multimeter automatically select the range
using the autoranging feature (select
AUTO
), or you may select a fixed
range using manual ranging (select
MANUAL
).
•
OFFSET COMP
: Allows you to enable (select
ON
) or disable (select
OFF
) the
offset compensation feature. With offset compensation enabled, the
multimeter makes a normal resistance measurement first, followed by a
second measurement to determine any offset voltage in the input
circuitry. The resultant displayed measurement corrects for this offset.
Enabling offset compensation increases measurement time.
• AUTO ZERO : Allows you to enable for all readings (select ON ), enable for
one reading (select ONCE ), or disable (select OFF ) the auto zero feature,
which subtracts a subsequent zero reading from each measurement
taken, to prevent offset voltages in the multimeter’s input circuitry from
affecting measurement accuracy.
•
NULL
: Allows you to enable (select
ON
) or disable (select
OFF
) the null
measurement feature, which measures the difference between a stored
null value and the input signal.
• NULL VALUE : Allows you to view and edit the null value.
