Amprobe DM7C Digital-Multimeter - Manual (Page 7)

Operation
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. Ab-
solutely 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.
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 voltages
exceeding 120V (60V) DC or 50V (25V)rms AC.
DC Voltage Measurement
1) Select measurement range (2V, 20V, 200V or 600V) via measurement
function selection switch.
2) Connect the black test lead to the COM socket and the red test lead to the
socket.
3) Connect test leads to UUT.
4) Read the measurement result displayed on the screen.
If display shows ”1” on the left, change selection to next highest voltage range.
AC Voltage Measurement
1) Select measurement range (200V or 600V) via measurement function
selection switch.
2) Connect the black test lead to the COM socket and the red test lead to the
socket.
3) Connect test leads to UUT.
4) Read the measurement result displayed on the screen.
If display shows ”1” on the left,, change selection to next highest voltage range.
