Programmable Detection Response Speed
Conventional withstanding voltage testers are generally used to only detect insulation breakdown, and cannot make judgements on instantaneous discharge currents like partial discharge.
However, the TOS9300 series is equipped with 5 levels of response speed settings to accurately detect low levels of insulation breakdown.Small discharges not visible to conventional withstanding voltage testers are easily detected with the TOS9300 series.
| Value | Description | |
| LPF | Slow | Mean-value response type current detector. This is similar to the current detection response of Kikusui's general-purpose AC withstanding voltage testers. This setting is suitable for detecting dielectric breakdown defined in safety standards and for general hipot tests for general electronic devices and components. This setting is not recommended for detecting corona discharge, which is not considered dielectric breakdown by typical safety standards. |
| Medium | Mean-value response type faster than SLOW setting. Upper limit judgement detection is much faster, suitable for withstanding voltage tests on compact electronic components and other EUTs prone to dielectric breakdown. Instantaneous discharges such as corona discharges with high frequencies are detected which may not be suitable for simple withstanding voltage tests. | |
| Fast | ||
| HPF | Slow | Extremely small discharges such as corona discharges are detected but with low reproductibility. |

I/V Monitor Terminal (Analog Monitor)
Signal outputs on the rear panel I/V terminal allow the user to monitor current/voltage waveforms during hipot tests with only an oscilloscope. Current sensors and high voltage probes not required.
Automatic Testing Feature
Tests can be combined and configured to execute automatically over long periods of time. Automotic tests are composed of programs and steps, which can be configured to initiate one after another.
