Current Measurements - Promax PD-183 Manual Del Usuario

4. When all measurements are completer, disconnect the test leads
from the circuit under test. Remove test leads from the multimeter.
For DC voltage readings, the RED lead tip should be connected to
the positive side of the circuit, the BLACK lead to the negative side.
A minus sign on the left hand side of the LCD will appear if the leads
are connected the other way round.

4.5 Current measurements

These are made in series with the test circuit. All the current to be
measured flows through the multimeter.
WARNING
Do not attempt to measure currents in high energy circuits
capable of delivering greater than 600V. Since the fuse is
rated at 600V damage or injury could occur. The 20A
input terminal is protected by a 20A/600V high energy,
fast blow fuse. The mA input terminal is protected by a
500mA/500V fast blow fuse.
Do not exceed the limits of each current input terminal. This is
20A (maximum time limit of 30 seconds for currents greater
than 10A) for the 20A terminal and 400mA for the mA terminal.
All current rages are fused. If a current greater than 20A on the 20A
range or greater than 500mA on all other ranges flows, the fuse will
blow causing an open circuit between the current measuring
terminals.
1. Insert the BLACK test lead in the COM input terminal.
