1 Model 3153  Automatic Insulation Voltage Withstand Testing Standards-Based Testing Voltage Control from a PC Full Remote Control Comparator/Timer All test parameters can be controlled by RS-232C or GP-IB, including test voltage, cut-off current, resistance threshold and timer durations. Start-stop control can be provided with the 9613 single hand remote control or 9614 twohand remote control. Includes built-in pass-fail comparator and timer functions for easy compliance testing to various safety standards such as those for Electrical Appliance Safety Regulations. Settable Ramp Up/Down Test...

Wide Range of Functions for Various Conditions^ 1. Pass Hold Function (0: No Hold, 1: Hold) The pass state is held when it is activated.This is convenient for verifying the decision value. 2. Fail Hold Function (0: No Hold, 1: Hold) The fail state is held when it is activated.This is convenient for temporarily stopping the test process. 3. Hold State (0: No Hold, 1: Hold) This saves the state when the Stop key is pressed during a test to unconditionally end the test. 4. Momentary Out (0: Disabled, 1: Enabled) This function outputs a voltage only when the Start key is being pressed. The Start...
