10.10 Procedures
(CH1): Resistance
(measure)
1.
Let the equipment get to a stable temperature (minimum: 5
minutes since the last power on).
2.
Use the calibration menu (
Section 10.3
) to do a two-point
calibration for each range.
•
Range: 0-400
Ω
a. Nominal zero ohms: Make a 4-wire connection to the 0
Ω
resistor; see
Section 3.2.9 (Example procedure: Measure
or simulate an RTD (or Resistance))
, example
A
.
b. Nominal positive full-scale ohms: Make a 4-wire
connection to the 400
Ω
resistor; see
Section 3.2.9
(
A
).
•
Range: 400
Ω
-4k
Ω.
a. Nominal 400 ohms: Make a 4-wire connection to the
400
Ω
resistor; see
Section 3.2.9
(A)
.
b. Nominal positive full-scale ohms: Make a 4-wire
connection to the 4k
Ω
resistor; see
Section 3.2.9
(
A
).
Note:
Details of the true ohms option to be issued later.
3.
To make sure the calibration is correct, select the applicable
Resistance (measure) function; see
Section 3.2.9
, (
A
).
4.
Make a 4-wire connection to the applicable standard resistor
(
Table 10-10
) and measure the value; see
Section 3.2.9
, (
A
).
5.
Make sure the error is in the specified limits (
Table 10-10
).
