Low Resistance Source Verification
Follow the subsequent steps to verify the low resistance source functions.
1. Two-wire low resistance source test:
a. Connect the 8588A to the low resistance source output terminals LO
Ω
HI and LO. Use a
four-wire connection and set the 8588A to four-wire measurement.
b. Set the
Low resistance source GND
item in low resistance source setup to GND On.
c. Select the LO
Ω
function on the Product. Push the
Mode
softkey and select
Resistance-
2W
.
d. Push
O
.
e. Use the rotary knob, cursor keys, or numerical keypad to set the output nominal range
value from 100 m
Ω
to 10 k
Ω
, see
.
f. Measure the Product resistance. Compare the measurement on the Product to the
limits in
2. Four-wire low resistance source:
a. Connect the 8588A +I and -I terminals to the low resistance source output terminals
LO
Ω
HI and LO. Connect the 8588A +
Ω
SENSE and -
Ω
SENSE terminals to the low
resistance source output terminals, LO
Ω
-SENSE HI and LO. Use a four-wire connection,
and set the 8588A to four-wire measurement.
b. Set
Low resistance source GND
in the Low resistance source setup to
GND On
.
c. Push
O
.
d. Measure the Product resistance. Compare the measurement on the Product with the
limits in
e. Select the LO
Ω
function on the Product. Push the
Mode
softkey and select
Resistance-
4W
.
f. Push
O
.
g. Use the rotary knob, cursor keys, or numerical keypad to set the output nominal range
value from 100 m
Ω
to 10 k
Ω
, see
.
h. Measure the Product resistance. Compare the measurement on the Product with the
limits in
3. SHORT Two-wire low resistance source test:
a. Connect the 8588A to the low resistance source output terminals LO
Ω
HI and LO. Use a
four-wire connection and set the 8588A to four wire measurement.
b. Set
Low resistance source GND
in the Low resistance source setup to
GND On
.
c. Select LO
Ω
function on the Product. Push the
Mode
softkey and select
SHORT 2-Wire
.
d. Push
O
.
e. Measure the Product resistance. The value reads
≤
100 m
Ω
