.
Figure 2-6. D.H Mode
In MAX, MIN mode, no further minimum, maximum, or average updates occur while the HOLD mode is enabled.
Auto HOLD Mode (A.H)
Warning
Auto HOLD mode does not capture unstable or noisy readings. Do not use Auto HOLD
mode to determine that circuits are without power.
Auto HOLD mode freezes the present reading in the primary display (The “
” is displayed). New readings now appear in
the secondary display. See Figure 2-7. When the meter detects a new, stable reading (>10% change from last stable reading),
it beeps and displays the new reading in the primary display.
Figure 2-7. A.H Mode
If you remove the test leads (open the input), the meter retains the last frozen primary display.
You cannot initiate Auto HOLD while MAX MIN, REL, TC, RTD, dBm, DC mV, AC mV, Diodes, continuity, Capacitance,
Frequency, or Duty cycle ratio function is active.
Peak HOLD Mode (A.H)
Note
Peak HOLD mode is only available in (DCV) .
In Peak HOLD mode, the meter detects, refresh, and displays the peak value in DCV
and display “
