B. AC Voltage Measuring
WARNING!
You can't input the voltage which more than 660V AC, it's possible to show higher voltage, but
may destroy the inner circuit.
Pay attention not to get an electric shock when measuring high voltage.
a. Connect the black test lead to the "COM" jack and the red test lead to the "V/Ω" jack.
b. Press and select
key, and manual range by pressing the
Manual range： 0.000V  6.600V range
C. DC Current Measuring (Manual Range ONLY!)
CAUTION!
Shut down the power of the tested circuit before making connections to the digital multi-meter!
a. Connect the black test lead to the "COM " jack and the red test lead
to the "mA" jack for a maximum of 660mA current. For a maximum
of 10A, move the red lead to the 10A jack.
b. Press to select
Manually adjust the range by pressing the
Manual range： 0.000mA  6.6mA range
ST-HDoC / ST-HDoC-MM
WARNING!
Input voltage not to exceed 660V DC!
Use extreme caution when measuring high voltage.
