! Measuring DC voltage and DC current on a transistor circuit or load.
To display DC voltage in primary display and the frequency in secondary
display or vise versus while testing a transistor amplifier circuit, user may
check its H
fe
or calculate its DC load consumption by using dual display.
1. Connect the meter to the unit under test as shown below:
2.
to select AC voltage measurement function for primary display.
3.
, or to select auto-ranging or manual range for
primary display.
4.
to turn on “ 2ND ” annunciator in secondary display.
5. to select Frequency (Hz) measurement function for secondary
display.
6.
, or to select auto-ranging or manual range for
secondary display.
Note: 1.
Press
then may turn off secondary display.
Note: 2.
Regarding secondary display function setting, please refer to Section 3-10.
WARNING!
1. Select a correct input terminal according to the input range to be used.
2. To avoid damaging the meter do not apply more than 12A to “
12A
” input terminal.
