Automatic Insulation Voltage Withstand Testing

Voltage Control from a PC

• Full Remote Control - 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 two-hand remote control.

• Comparator/Timer - 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.

• Ramp Timer Functions - Raising and lowering of test voltage can be set for voltage withstand testing.
  

• Program Function - Test conditions can be stored and recalled to support complete automation by sequencer. Up to 32 files can be stored with up to 50 steps per file.
  
  
• Automation Support
  Automation features include programmable testing modes, EXT I/O, RS-232C, GP-IB, connection scanning and various data management functions.
• Auto Discharge Feature
  Any charge on the object under test is discharged by the test instrument, so there is no residual charge after testing. (DC voltage withstand, insulation resistance tests)
• Save 10 Sets of Test Conditions
  Store up to 10 sets of test conditions for voltage withstand and insulation resistance modes, so you can quickly switch among the test conditions. (Save/Load)
• Zero-V Switching
  Test voltage on/off switching can be forced to occur only at sine wave zero-crossings. (AC voltage withstand testing)
• Interlock Protect Function
  To ensure safety during automatic testing, test output can be interrupted and testing inhibited by input signals from automatic sensing devices.
• PWM Switching Technique
  Enhanced accuracy is obtained by preventing variations in supply voltage from affecting test voltage.
   

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 key is effective both for EXT SW and external I/O.

5. Double Action (0: Disabled, 1: Enabled)
This function allows testing to start only if the Start key is pressed within a half second after the Stop key.
    
6. Fail Mode (0: Disabled, 1: Enabled)
This function allows the Hold state to be released only by the Stop key on the instrument panel.

7. "START" Interface Command (0: Disabled, 1: Enabled)
This specifies whether the "START" command is enabled.

8. Interlock Function (0: Disabled, 1: Enabled)
This specifies whether the interlock terminal for external I/O is enabled.

9. Maximum Output Voltage
Sets the upper limit of the test voltage.
    
10. Insulation Resistance Measurement Range (0: Fixed Range, 1: Automatic Range)
This specifies whether the measurement range for insulation resistance testing should be fixed or automatically determined.

11. Insulation Resistance Test End Mode
0: Test for the specified time
1: Stop when "pass" is detected
2: Stop when "fail" is detected
This specifies the method of ending insulation resistance tests.

12. Ramp Time Setting
0: No judgment during ramp-up
1: Judgment during ramp-up
This specifies whether the judgment is enabled during ramp-up. Valid only during voltage withstand testing.

13. PC Interface
0: RS-232C (PC, 9600 bps)
1: RS-232C (PC, 19200 bps)
2: GP-IB
This specifies the type of PC interface to use.

14. Electrical Discharge Function (0: Disabled, 1: Enabled)
This specifies whether the electrical discharge function is enabled at the end of testing.

15. Test Signal Output
0: ON also when TEST indicator is flashing
1: OFF when TEST indicator is flashing
2: ON only when TEST indicator is flashing
This specifies whether the TEST signal of the external I/O should be outputwhen the TEST indicator is flashing.
