3. OPERATION
3.1. Precautions
Warning: Before using the instrument, read the Safety Information
Section, and examine it for damage or contamination (excessive dirt,
grease, etc.). Check the test leads for any evidence of cracked or
frayed insulation. If any abnormal conditions exist, do not use the
meter.
Warning: When using probes, keep your fingers behind the guards.
Warning: Measuring voltages which exceed the limits of the meter
may damage it and expose the operator to a shock hazard. Always
work within the meter voltage limits indicated on it's front panel.
Warning: Never ground yourself when taking electrical
measurements. Do not touch exposed metal pipes, outlets, fixtures
etc. which may be at ground potential. Keep your body insulated by
wearing dry clothing, rubber shoes or stand on a rubber mat, or other
suitable material.
3.2 Voltage measurement
1. Connect the red test lead to the "V
Ω
" socket, and the black lead to the
"COM" socket.
2. Select the correct function & range using the rotary switch, ensuring that
AC, or DC, ranges are chosen as appropriate. If the magnitude of the
signal is uncertain, then begin with the highest setting, and reduce it until a
satisfactory indication is obtained.
3. Connect the other end of both test leads to the unit under test.
4. In the DC function a "-" is displayed for negative values, positive
indication is implied.
