Questions answered in GWINSTEK manuals
How should the GPM‑8213 be stored when not in use?
Store the instrument indoors at temperatures between –40 °C and 70 °C, with humidity below 90 % RH and no condensation.
Why does the output still turn on/off after pressing the panel lock key?
The output key is not controlled by the panel lock key, so locking the panel does not affect output operation.
From: GW Instek GPD-2303S/3303S/4303S Series DC Power Supply User Manual
Why are saved settings not turning the output on after recall?
Saved settings default the output to the "off" state for safety, so the output remains off after recall.
From: GW Instek GPD-2303S/3303S/4303S Series DC Power Supply User Manual

It offers five DC voltage ranges: 100 mV, 1 V, 10 V, 100 V, and 1000 V.
