4.8 Remote Measurement Function
When the load consumes high current, the power supply will produce voltage drop in the connecting wire
between power supply and load terminals. In order to guarantee the measurement accuracy, remote
measurement terminals is installed at the rear-panel of the power supply. Users can measure the output
terminals voltage of the instrument under test by these terminals.
Before performing the remote measurement function, you need to set the power supply as the remote
measurement mode.
Please refer to the diagram 4.4 for the trigger terminals and measurement terminals.
Diagram 4.4 Remote Measurement Terminals
-S and +S are remote measurement terminals; TRQ and TRI are trigger terminals, GND is ground terminal.
The TRQ is trigger output port under auto test mode. The TRQ is default as low voltage level. The TRQ
pr5V for external use when the trigger event happens.
As a multifunction extended port, TRI port is designed for trigger test in the list mode and auto test mode, TRI
is also used to switch the ON/OFF state and used as TRI KeepOut port. The TRI is default as high voltage level
of +5V. The TRI completes trigger when it change to low voltage level.
4.9 Milliohmmeter Function
The power supply provides the four-line electrical resistance measurement, just as showed in following
diagram 4.5, which can measure accurately the low resistance and the maximum measurement resistance is
10Ω. In order to avoid the damage of the resistance under test, please make sure the resistance under test is
within the measurement range.
Three measurement ranges can be optional: 0.1W, 1W, 10W.
Operation Method:
1) Press the keys
and
V/m
Ω (VFD display screen shows----,----mΩ, Range:0.1W) to measure the
resistance.
2) Press the keys
and
0.1W
or
1W
or
10W
to set different measurement range of Milliohmmeter.
