Special Features
Amps inrush
Continuous fast sampling captures the peak inrush current
Ballast mode for testing the output of electronic lighting ballast
Reliable measurements of tube current and power
Optional Interface Cards
IEEE488 for high speed control and data capture
RS232 and parallel printer interface. The RS232 serial port allows complete command and results handling as IEEE488. The parallel printer port may be connected directly to a standard printer with a parallel interface for printing displayed or numeric results.
Chart recorder and alarm interface. Twelve 0-5V DC outputs track any measurement parameter desired. Two free relay contacts can be programmed to toggle at any selected level for alarm or process control purposes. The twelve chart recorder outputs may also be configured as digital alarm
