34410A/11A/L4411A User’s Guide 69
Features and Functions 2
• Auto triggering is a front panel mode similar to immediate triggering from the remote
interface, but also sets the sample count to infinite and automatically initiates
continuous measurements.
• To enable auto triggering, press
TRIGGER > AUTO
Single Triggering (34410A/11A)
This mode is available from the front panel only.
• The multimeter takes one reading, or a number of readings specified by a sample
count you enter, each time you press , or upon receiving an external trigger
signal on the rear-panel Ext Trig connector (see “External Triggering” on page 76).
See also “Number of Samples per Trigger” on page 71.
• The Trig annunciator indicates that the multimeter is waiting for a trigger.
Reading Hold (34410A/11A)
This mode is available from the front panel only.
The reading hold mode allows you to capture and hold a stable reading on the front
panel display. This is useful in situations when you want to take a reading, remove the
test probes, and have the reading remain on the display. When a stable reading is
detected, the multimeter emits a beep (if the front–panel beeper is enabled) and holds the
reading on the display.
• The sensitivity band for reading hold depends on the measurement function that is
selected. The multimeter captures and displays a new value only when reading
stability is detected.
• Reading hold is disabled if you change measurement functions, or if you change to
remote mode.
• The currently configured range (auto or manual) is used for reading hold. If you
manually select a new range, reading hold is disabled.
• To enable reading hold, press
TRIGGER > HOLD
• The Hold annunciator is lit.
• Each time a stable reading is detected, the reading is displayed and the beeper
sounds (if enabled).
