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.

In Peak HOLD mode, the meter detects, refresh, and displays the peak value in DCV and display “ ”. (See figure 2-8).
Figure 2-8.P.H Mode
Peak HOLD mode could capture the signals of an imminent of a positive polarity as short as 1 ms except that the accuracy is low.
In Peak HOLD mode, press to calculate the relative value and the screen will show symbol “ ”and the relative peak
value.
Press
to clear the value off and the new peak value would be captured.

In measurement mode, press enter into relative mode and the meter displays the present reading as a reference in the
secondary display and the relative value in the primary display (The difference between the reference and a new measurement).
Press again to exit the mode.
This function is available with all functions except frequency/duty cycle ratio, MAX MIN, TC, RTD, dBm measurement.
