Features and Functions 2
Configuring Frequency and Period Measurements
For frequency and period measurements, your configuration menu choices
are: CONFIGURE, GATE TIME, RANGE, AC FILTER, NULL and NULL VALUE.
• CONFIGURE: Allows you to select either FREQUENCY or PERIOD as the
primary measurement.
• GATE TIME: Allows you to select one of four choices (0.001, 0.01, 0.1 or 1)
for measurement gate time, in seconds.
• 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).
• 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.
• 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 Temperature Measurements
For temperature measurements, your configuration menu choices are:
PROBE TYPE, OFFSET COMP, AUTO ZERO, INTEGRATION, NULL, NULL VALUE, and UNITS.
• PROBE TYPE: Allows you to select from four choices (RTD–4W, RTD–2W,
THERMISTOR–2W, or THERMISTOR–4W) of temperature probe type.
• OFFSET COMP (for RTD probes only): Allows you to enable (select ON) or
disable (select OFF) the offset compensation feature. With offset
compensation enabled, the multimeter makes a normal temperature
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 (for 2–wire thermistor probes only): Allows you to enable
(select ON) 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.
