Features and Functions 2
• RANGE: Allows you to let the multimeter automatically select the range using the
autoranging feature (select AUTO), or you may select a fixed range (select
MANUAL).
• NULL: Allows you to enable (ON) or disable (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 (if enabled).
Continuity and Diode Tests
There are no parameters to configure, nor any menus for these functions.
• Continuity Test. The range and resolution are fixed for continuity tests.
• The range is 1 kΩ (a 2-wire resistance measurement).
• The meter beeps (even if beep is disabled) for each measurement that is less than
or equal to the continuity threshold (which is 10 Ω), and the actual resistance
reading is displayed on the front panel.
• From 10 Ω to 1.2 kΩ the meter displays the actual resistance reading with no
beep. If the reading exceeds 1.2 kΩ, the meter displays "OPEN" on the front panel
(no beep).
• Diode Test. The range and resolution are fixed for diode tests.
• The range is 1 Vdc (with a 1 mA current source output).
• The voltage is displayed on the front panel if it is in the 0 to 1.2 volt range. The
meter beeps when the signal transitions to the 0.3 to 0.8 volt threshold (unless
beep is disabled). If the signal is greater than 1.2 volts, "OPEN" is displayed on
the front panel.
