General specifications apply for the temperature range 5°C to 40°C. Accuracy specifications
apply for the temperature range 18°C to 28°C after 1 hour warm-up with no load and calibration at
23°C. Typical specifications are determined by design and are not guaranteed.

modes via front panel rotary switch.
The voltage adjustment range can be controlled by digital setting of the
end-stop values of the coarse voltage control to any desired values.
The range for Vmax is 0.1V to 15V/30V/60V depending on model.
The range for Vmin is 0 to (Vmax – 0.1V).
Voltage and current settings can be locked by a single button press.
Lock accuracy is equal to meter accuracy (see Meter Specification)
