Conguring Generator-Module-Specic Settings

Comprehensive test

The instrument outputs the following voltages and currents of each output function and each

generation range, measuring them with the internal measurement circuit. Then, the instrument

sends back measured values of each output value.

CAUTION

Do not connect anything with the OUTPUT terminal during comprehensive tests. The

instrument outputs a zero-volt signal and connects the OUTPUT terminal with the GND

terminal (in the short-circuit state) during comprehensive tests. If a power supply device

connects with the instrument, a short-circuit current will ow, resulting in damage to the

instrument or power supply device. The comprehensive test results may be affected

depending on devices connected.

Offset canceling function

Regulating the zero point of the output circuit

The instrument measures an output circuit offset with the internal measurement circuit and outputs

a value the offset value is subtracted from.

CAUTION

Do not connect anything with the OUTPUT terminal during an offset measurement. The

instrument outputs a zero-volt signal and connects the OUTPUT terminal with the GND

terminal (in the short-circuit state) during the offset measurement. If a power supply

device connects with the instrument, a short-circuit current will ow, resulting in damage

to the instrument or power supply device. The results (zero-point regulation) may be

affected depending on devices connected.

To perform precise measurement

IMPORTANT

Be careful of the following points when the instrument outputs a current of 100 µA or less with

the current output function, when it generates a resistance of 50 k

or more with the resistance

generation function, or when a device connected with the instrument has an output resistance of

50 k

• We recommend you to use measurement cables with an insulating sheath made of

polyethylene (PE) or polytetrauoroethylene (TFE). Using measurement cables with a low-

resistance insulating sheath will increase leak currents, with the result that accuracy is

signicantly affected.

• The instrument will become susceptible to exogenous noise. We recommend you to use

shielded measurement cables or connect a capacitor between the OUTPUT terminal and GND

terminal.
