*2. Measurement frequency bandwidth is 5 Hz to 1 MHz.

*3. Measurement frequency bandwidth is 10 Hz to 20 MHz.

*4. From 10%~90% of rated output voltage, with rated resistive load.

*5. From 90%~10% of rated output voltage, with rated resistive load.

*6. Temperature coefficient: after a 30 minute warm-up.
