3.2.7 Other features of main outputs
- Zero crossing control. Main AC outputs are generated and stopped as the output waveform is zero.
This implies that in mode ON+TIME the output drops to zero with a delay from 0 to one cycle after
STOP is detected.
- Over-current alarm message.
- Thermal protection: by NTC. The operator is alerted by a message.
- Output adjustment: from less than 5% to 100% of the output.
- Output measurement. The used output is software selected; the selected socket is confirmed by a
light.
3.3 AUXILIARY CONTACT
- Possibility to delay the auxiliary contact switch with respect to test start. Delay range: from 0 to
99.99 s.
- Contacts range: 5 A; 250 V AC; 120 V DC
