INSTRUCTION MANUAL
AC voltage measurement
• Select V AC measurement mode via measurement function selection switch.
•
Connect the black test lead to the COM socket and the red test lead to the
V Ω mA °C Hz%
• Connect test leads to UUT (circuit / unit under test).
• Read the measurement result displayed on the display.
DC voltage measurement
• Select VDC measurement mode via measurement function selection switch.
• Connect the black test lead to the COM socket and the red test lead to the
V Ω mA °C Hz%
• Connect test leads to UUT.
• Read the measurement result displayed on the display.

Frequency measurement

• Select Hz% measurement mode via measurement function selection switch.
• Connect the black test lead to the COM socket and the red test lead to the
V Ω mA °C Hz%
• Connect the test leads to UUT.
• Read the measurement result displayed on the display.

Resistance measurement

Prior to any resistance measurement it has to be ensured that the resistor to be
tested is not live. Failure to comply with this prescription can lead to dangerous
corporal user injuries or cause instrument damage. Additionally, foreign voltages
falsify the measurement result.
• Select
• Connect the black test lead to the COM socket and the red test lead to the
V Ω mA °C Hz%
• Connect the test leads to UUT.
• Read the measurement result displayed on the display.

Diode test

Prior to any diode test, it must be ensured, that the diode to be tested is not
live. Failure to comply with this prescription can lead to dangerous corporal user
injuries or cause instrument damage. Additionally, foreign voltages falsify the
measurement result.
Resistors and semiconductor paths in parallel to the diode cause falsified
measurement results.
• Select
• If necessary, use SELECT button to set the measurement. Press SELECT button
to cycle through resistance, continuity, diode and capacitance measurements.
• Connect the black test lead to the COM socket and the red test lead to the
V Ω mA °C Hz%
• Connect test leads to UUT.
• Read the measurement result displayed on the display.

Continuity test

Prior to any continuity test, it must be ensured that the resistance to be meas-
ured is not live. Failure to comply with this prescription can lead to dangerous
corporal user injuries or cause instrument damage. Additionally, foreign voltages
falsify the measurement result.
