· Settling time: 0 – 600,0 s
· Test time: 0 – 600,0 s
· Power off end of test: Yes
1.1.5 Current and power in synchronism
The tests are intended to synchronize the absorption measurements with an event (action of an operator) that during the test phase varies some test conditions. Is a classic application of electric cookers, each knob position is linked to a different value of power consumption. The test time is fixed and the synchrony between the operator and the tester is facilitated by an acoustic signal when the measure has been successful and the instrument is waiting for a new variation. The tests are divided between current measures and measures in watts.
Parameters
· Measure range: 0 – 50,00 A or 0 – 11000 W
· Reference threshold: 0 – 50,00 A or 0 – 11000 W

· Max time: 0 – 600,0 s
· Power at and of test: Yes / No
1.1.6 Auto Mode / Manuel Steps Mode
The test goes on automatically from start till end of the test in Auto Mod. In the case of safety fail occurring it stops and pause the test.
In Manuel step mode the operator can control whole the steps himself as step by step.
1.1.7 Thermal printer (Optional)
Will be provided the customer with a thermal printer panel, connected at the serial port usb.
