4. MEASURING PROCEDURE
4-1 Measuring procedure
1)Power on by pressing the " power on/off key ", the all
segments of LCD will be ON for 2 seconds
﹒
2)The default mode is AUTO LCR smart mode and the
default test frequency is 1 KHz.
3)In order to extend the battery life
﹐
it is recommended
to use the external power supply and the APO setting (
Auto power off setting ).
﹒
When all function button do
not be push within 5 minutes
﹐
the system will launch
the alarm buzzer beep at three times before the
power-off state
﹒
4)When AUTO/L/C/R function selection button ( L/C/R ) is
pushed
﹐
the main test mode could be selected
sequentially
：
Auto-LCR mode Auto-L mode
→
→
Auto-C mode Auto-R mode
→
→
DCR mode Auto-LCR mode.
→
The default test mode is Auto LCR mode which
could check the type of impedance smartly and enter
to the L/C/R measurement mode automatically
﹒
The
secondary parameter will follow the L/C/R
measurement
﹒
When Auto-L or Auto-C mode is selected, the
impedance measurement is auto ranging.
The primary LCD display will show the inductance or
capacitance of DUT ( device under testing ). The
secondary LCD display will show the quality ( Q ) or
dissipation ( D ) factor.
