10.1 DC VOLTAGE MEASUREMENT
1.
Connect the red test lead to the "V" jack and the black lead to the
"COM" jack.
2.
Set the rotary switch in the desired V
measured is unknown beforehand, you should set the range switch in
the highest range position and then reduce gradually until the ideal
resolution is obtained.
3.
Connect the test leads to the source being measured.
4.
Read the voltage value on the LCD display along with the polarity of
the red lead connection.
10.2 AC VOLTAGE MEASUREMENT
1.
Connect the red test lead to the "V" jack and the black test lead to
the "COM" jack.
2.
Set the rotary switch in the appropriate V~ position.
3.
Connect the test leads to the source to be measured.
4.
Read the voltage value on the LCD display.
11. Current Measurement
Do not measure circuits that may contain voltages > 700 V
Use extreme caution when measuring voltages higher than 60 VDC
or 30 VAC rms.
Always place your fingers behind the protective edges of the test
probes while measuring!
11.1 DC CURRENT MEASUREMENT
1.
Connect the red test lead to the "mA/BATT/°C" jack and the black test
lead to the "COM" jack (switch the red lead to the "15A" jack for
measurements between 200 mA and 15 A).
2.
Set the rotary switch in the desired A
3.
Open the circuit in which the current is to be measured and connect
the test leads to the circuit IN SERIES.
4.
Read the current value and the polarity of the red lead connection on
the LCD display
V. 01 – 30/08/2016
