MIN MAX AVG Recording Mode
The MIN MAX AVG recording mode captures the minimum and
maximum input values, and calculates a running average of all
readings. When a new high or low is detected, the Meter beeps.
Note
For dc functions, accuracy is the specified accuracy of the
measurement function
±
12 counts for changes longer than
275 ms in duration.
For ac functions, accuracy is the specified accuracy of the
measurement function
±
40 counts for changes longer than
1.2 s in duration.
To use MIN MAX AVG recording:
⇒ Make sure that the Meter is in the desired measurement
function and range. (Autoranging is disabled in the MIN MAX
AVG mode.)
⇒ Press MIN MAX to activate MIN MAX AVG mode.
m and MAX light, and the highest reading detected
since entering MIN MAX AVG is displayed.
⇒ Press MIN MAX to step through the low (MIN), average
(AVG), and present readings.
⇒ To pause MIN MAX AVG recording without erasing stored
values, press HOLD. h is displayed.
To resume MIN MAX AVG recording, press HOLD again.
h turns off.
⇒ To exit and erase stored readings, press MIN MAX for 1
second or turn the rotary switch.
AutoHOLD Modes
XWWarning
To avoid electric shock, do not use the AutoHOLD mode
to determine if a circuit is live. Unstable or noisy
readings will not be captured.
In the AutoHOLD mode, the Meter holds the reading on the display
until it detects a new stable reading. Then the Meter beeps, and
displays the new reading.
⇒ Press HOLD to activate AutoHOLD. h lights.
⇒ Press HOLD again or turn the rotary switch to resume normal
operation.
YELLOW Button
Press the yellow button to select alternate measurement functions
on a rotary switch setting, e.g., to select DC mA, DC A, Hz,
capacitance, or diode test.
Display Backlight
Press S to toggle the backlight on and off. The backlight
automatically turns off after 2 minutes.
