Press
EXIT
to return to normal display.
8.
Push
OUTPUT
to turn the output on and then press
TRIG
. A 2-second delay occurs before
the first measurement. The unit cycles through measurements indefinitely with a 1s interval
between measurements.
9.
Turn off the
OUTPUT
to stop taking readings.
Measure only
In addition to being used for conventional source-measure operations, the Series 2600A can also
be used to measure only voltage or current. Perform the following steps to use the Series 2600A to
measure voltage or current:
1.
Select source-measure functions.
Measure voltage only (voltmeter): Press
SRC
to select the I-Source, and press
MEAS
to
select the voltage measurement function.
Measure current only (ammeter): Press
SRC
to select the V-Source, and press
MEAS
to
select the current measurement function.
2.
Set source and compliance levels.
Use the editing procedure provided in steps 1 and 2 of the
to edit the source and compliance levels:
a.
Select the lowest source range and set the source level to zero (000.000nA or
000.000mV, 0.00000nA for Models 2635A/2636A).
b.
Set compliance to a level that is higher than the expected measurement.
CAUTION
When using the Series 2600A as a voltmeter, V-Compliance must be set
higher than the voltage that is being measured. Failure to do this could
result in excessive current flow into the Series 2600A (<150mA) and
incorrect measurements.
3.
Select range:
Use the
RANGE
keys to select a fixed measurement range that will accommodate the
expected reading. Use the lowest possible range for best accuracy.
When measuring the function opposite from the source function, AUTO range can be used
instead. The Series 2600A automatically goes to the most sensitive range.
4.
Connect voltage or current to be measured. Connect the DUT to the SourceMeter
instrument using 2-wire connections (see
5.
Turn output on. Press the
ON/OFF
key to turn the output on.
6.
Take reading from display (press
TRIG
if necessary). When finished, turn output off.
