| Item/Model | TOS5300 | TOS5301 | TOS5302 |
|---|
| Double action feature | Tests can only be started by pressing and releasing STOP and then pressing START within 0.5 seconds of releasing the STOP switch. |
|---|
| Length of time to maintain a PASS judgment result | You can set the length of time to maintain a PASS judgment: 50 ms, 100 ms, 200 ms, 1 s, 2 s,5 s, or HOLD. |
|---|
| Momentary feature | Tests are only executed while the START switch is held down. |
|---|
| Fail mode feature | This feature enables you to prevent remotely transmitted stop signals from clearing FAIL judgments and PROTECTION modes. |
|---|
| Timer feature | This feature finishes tests when the specified time elapses. |
|---|
| Output voltage monitor feature | If output voltage exceeds “setting + 350 V” or is lower than “setting – 350 V,” the TOS5200 switches to PROTECTION mode, output is turned off, and testing finishes. |
|---|
| Memory | Up to three sets of test conditions can be saved to memory. |
|---|
| Key lock | Locks panel key operations (settings and changes). |
|---|
| Protective features | | Under any of the following conditions, the TOS5300 Series switches to the PROTECTION state, immediately turns output off, and stops testing. A message is displayed on the screen. |
|---|
| Interlock Protection | An interlock signal has been detected. |
|---|
| Power Supply Protection | An error was detected in the power supply. |
|---|
| Volt Error Protection | While monitoring the output voltage, a voltage outside of the rated limits was detected. AC or DC withstanding voltage tests: ±350 V Insulation resistance test: ±(10 % of set + 10 V) |
|---|
| Over Load Protection | During a withstanding voltage test, a value that is greater than or equal to the output limit power was specified. AC withstanding voltage test: 550 VA. DC withstanding voltage test: 55 VA. |
|---|
| Over Heat Protection | The internal temperature of the TOS5200 became too high. |
|---|
| Over Rating Protection | During a withstanding voltage test, the output current was generated for a length of time that exceeds the regulated time. |
|---|
| Calibration Protection | The specified calibration period has elapsed. |
|---|
| Remote Protection | A connection to or disconnection from the front- panel REMOTE connector was detected. |
|---|
| SIGNAL I/O Protection | The rear-panel SIGNAL I/O connector’s ENABLE signal has changed. |
|---|
| USB Protection | The USB connector has been disconnected while the TOS5300 Series was being controlled through the USB interface. |
|---|
| System clock | | Set in the following format: year/month/day hour/minutes/seconds. |
|---|
| Calibration date | Set when the TOS5300 Series is calibrated. |
|---|
| Calibration period setting | Sets the period before the next calibration is necessary. |
|---|
| Notification of when the calibration period elapses | Sets the operation that is performed when the specified calibration period elapses. When the TOS5300 Series turns on, it can display a notification or switch to the protection mode and disable testing. |
|---|
| Interface | USB | USB Specification 2.0 |
|---|
| REMOTE | Front-panel 9-pin MINI DIN connector. By connecting an optional device to this connector, you can control the starting and stopping of tests remotely. |
|---|
| SIGNAL I/O | Rear-panel D-sub 25-pin connector |
