Carrying out measurements
Commissioning
General Information to carry out measurements:
Measurements in dangerous proximity of electrical systems are only to be
carried out in compliance with the instructions of a responsible electronics
technician, and never alone.
Test leads and test probes may only be touched at handle surfaces provided.
Absolutely avoid the direct contact of the test probes. Prior to switching to a
new measurement range or a new type of measurement, remove all connections
from UUT (circuit / unit under test).
Measurements have to be carried out by respecting the standards.
Voltage measurement
To avoid electrical shock, the valid safety measures and VDE directives strictly
have to be met concerning excessive contact voltage when working with volt-
ages exceeding 120 V (60 V) DC or 50 V (25 V) rms AC. The values in brackets
are valid for limited areas (such as e.g. medicine, agriculture).
AC voltage measurement
• Select VAC or VSCAN measurement mode via measurement function selection
switch.
• Connect the black test lead to the COM socket and the red test lead to the
mV Ω μmA °C Hz
socket.
• Connect test leads to UUT.
• Read the measurement result displayed on the display.
DC voltage measurement
• Select VDC or VSCAN measurement mode via measurement function selection
switch.
• Connect the black test lead to the COM socket and the red test lead to the
mV Ω μmA °C Hz
socket.
• Connect test leads to UUT.
• Read the measurement result displayed on the display.
AC mV voltage measurement
• Select mV measurement mode via measurement function selection switch.
• Multimeter will automatically enter in mV AC mode.
• Connect the black test lead to the COM socket and the red test lead to the
mV Ω μmA °C Hz
socket.
• Connect test leads to UUT.
• Read the measurement result displayed on the display.
DC mV voltage measurement
• Select mV measurement mode via measurement function selection switch.
• Press “Select” button once to enter mV DC measurement mode.
• Connect the black test lead to the COM socket and the red test lead to the
mV Ω μmA °C Hz
socket.
• Connect test leads to UUT.
• Read the measurement result displayed on the display.
NCV (Non-contact voltage measurement)
• Select NCV measurement mode via measurement function selection switch.
• Point the top of the 45215 multimeter, which is labelled with NCV, towards the
source of the electric field (power cable, power socket or light switch).
• Read the measurement result displayed on the display (stronger the electric
field multimeter detects, more horizontal lines will appear on the LCD and faster
beeping will be heard. If Multimeter detects no electric field it will indicate “EF”
on the LCD).
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
mV Ω μmA °C Hz
socket.
• 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 Ω
measurement mode via measurement function selection switch.
• 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
mV Ω μmA °C Hz
socket.
• Connect the test leads to UUT.
• Read the measurement result displayed on the display.
Continuity 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 Ω
measurement mode via measurement function selection switch.
• 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
mV Ω μmA °C Hz
socket.
• Connect the test leads to UUT.
• Read the measurement result displayed on the display.
Acoustic indication by signal sound if resistance < 30 Ω.
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 Ω
measurement mode via measurement function selection switch.
• 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
mV Ω μmA °C Hz
socket.
• Connect test leads to UUT.
• Read the measurement result displayed on the display.
