BASIC OPERATION

use the up and down keys to select the required
range, press Enter to confirm and exit the editing
state.
Sync
cmpl
range
Setting measurement reading range to synchronize
with compliance range, the default setting is Disable
when power-on. To enable Sync cmpl range, Auto
for Measure volt-range or Measure curr-range
should be deselected, that is, turn off the Auto range
function. When Sync cmpl range is selected as
Enable, the measurement reading range can be
automatically synchronized with the Cmpl range.
Sense
mode
The basic source-measure operations of GSM
performed using 2-wire local sense connections or 4-
wire remote sense connections.
2-wire sense connection
: Bench and GPIB power on
default using 2-wire sense connection. 2-wire sense
connection can only be used when the voltage drop
generated by the test lead resistor can be accepted.
When the loop current is lower than 100mA, the
error caused by the test lead resistor can be ignored
(assuming that the test lead resistor is less than 1Ω).
2-wire sense connection is used for voltage and
current measurement.
4-wire sense connection
: reduce the error caused by
the test lead resistor, and optimize the output
voltage accuracy and measurement accuracy. When
used as a V-Source, load the programmed voltage to
the load without loss. When used as a voltmeter, the
measurement reading is the voltage drop on the
load. The following two situations should choose 4-
wire sense connection:
a
DUT resistor is less than 1kΩ
b
The best accuracy of resistor, output voltage or
voltage measurement reading is required
