4. Using the Meter
4.1 Data Hold
4.1.1 During measurement, if you want to keep the
reading on the display, press“HOLD”and the
reading will be held.
4.1.2 Press“HOLD”again to release the hold.
4.2 Manual Range
4.2.1 In voltage, current, resistance, capacitance, and
frequency modes, the default range is auto.
4.2.2 Press“RANGE”to switch to manual range.Each
press of the button increases the range, and returns
to the lowest range when pressed in the largest
range.
4.2.3 Hold down“RANGE”for 1 second to return to auto
range.
4.2.4 When in Max/Min modes, pressing“RANGE”to
return to normal measurement.
Note:
Frequency cannot be set to manual range.
4.3 Relative Mode
4.3 1 Press“REL”to enter relative mode.The meter stores
the measured value when the button was pressed
and compares it to the currently measured value
(rel = current reading - stored reading).
.
4.4 Maximum/Minimum Mode
4.4.1 Press MAX/MIN in any range to show the maximum
value recorded; press“MAX/MIN”again to show the
minimum value recorded; press“MAX/MIN”a third
time to return the display to normal.
