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
• 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
• 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
• 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
• 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).
