Connecting the Output Terminal
1
Insert the plug of the measurement lead into the output terminal of the instrument.
2
Pinch the terminals on the target device with the clips on the other side of the lead.

Wiring generating resistance or RTD (3-line or 4-line wiring)
The use of optional input-terminal adapters makes it easy to implement 3-line or 4-line
wiring. Input-terminal adapter is an adapter for conversion from safety terminal to
binding post.
Prepare wire rods in stead of the typical measuring lead and connect it as shown in the
following figure (for a three-wire system).

CAUTION
• Do not apply voltage to the output terminal except when the
instrument is in the current-generation mode. Otherwise, the
internal circuitry may be damaged.
• Since this instrument is calibrated with the voltage drop of the
measurement lead excluded, an error due to the resistance at
the measurement lead (approx. 0.08
Ω
) must be considered.
Before Generation
For accurate generation, be sure to perform auto-zero calibration (i.e., cancel the offset
error) before generation.
Effects of executing auto-zero calibration
• During measurement: The displayed data of measurement are held until the auto-zero
calibration ends, and sampling is also interrupted if applicable.
• When averaging is enabled: The accumulated data for a moving average is discarded,
and a new averaging process starts as the auto-zero calibration ends.
1
Press the [FUNCTION] key on the SOURCE side until [CAL/no] is displayed.
2
Press the [ ] or [ ] key to change the lower display to [YeS].
3
Press the [NEXT ENTER] key to execute auto-zero calibration.
4
After completing auto-zero calibration, the function switches to DCV.
