*1 When tests are performed consecutively, output time limit and rest time may become necessary depending on the upper limit setting *2 If an AC voltage is applied to a capacitive load, the output voltage may rise higher than at no load depending on the load capacitance. Further, waveform distortions may occur if an EUT whose capacitance is dependent on voltage (for example, an EUT that consists of ceramic capacitors) is connected as the load. However, if the test voltage is 1.5 kV, the effect of a capacitance of 1 000 pF or less can be ignored. Because the product’s high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise proportions are large. The lower the test voltage, the greater the waveform is distorted.

I | Current waveform: Scale 50 mA/1 V | ||||||
V | Voltage waveform: Scale 1 kV/1 V | ||||||
Grounding mode (GND) | Can be switched between Low and Guard. | ||||||
Low | GND is connected to the low terminal. Measures the current flowing across the low terminal and chassis (normal applications). | ||||||
Guard *2 | GND is connected to Guard. Measures only the current flowing through the low terminal (cur-rent flowing through the chassis is not measured) (high sensitivity, high accuracy measure-ment applications). |
*1 Monitor signal output is isolated from the chassis (earth). If you connect an oscilloscope or an external device whose BNC shield is grounded, be sure to set the grounding mode (GND) to Guard. The value is not calibrated. *2 If there is a possibility that the EUT or tools and the like will be grounded or if you are uncertain, do not set GND to Guard. Doing so is extremely dangerous because the ammeter will be shorted and will not be able to measure current. For normal applications, set GND to Low.

*1 Humidity: 70 %rh or less (no condensation), when there is no interference caused by wobbly test leads or other problems. *2 If the grounding mode (GND) is set to low in a highly humid environment, leakage current to ground will be generated from the high-voltage wiring sections inside the product and the high-voltage wiring sections between the product and the EUT. This leakage current ranges from several nA to several tens of nA depending on the usage and wiring conditions of the optional TOS9320 high voltage scanner and greatly affects measurement accuracy. The effects of leakage current can be reduced by making measurements with the offset enabled. *3 Add 10 % to the accuracy when measuring 100 V or less. *4 Add 5 % to the accuracy when measuring 100 V or less. *5 When the measured current is limited to 100 nA or more (no condensation) when the humidity is 50 %rh or less, no external disturbance is present such as swinging test leads, and the offset is enabled.

*1 Making judgments on 200 μA or less requires at least 3 seconds after the rise time ends. Making judgments when the low pass filter is set to on requires at least 10 seconds after the rise time ends. *2 Humidity: 70 %rh or less (no condensation), when there is no interference caused by wobbly test leads or other problems. *3 If the grounding mode (GND) is set to low in a highly humid environment, leakage current to ground will be generated from the high-voltage wiring sections inside the product and the high-voltage wiring sections between the product and the EUT. This leakage current ranges from several nA to several tens of nA depending on the usage and wiring conditions of the optional TOS9320 high voltage scanner and greatly affects measurement accuracy. The effects of leakage current can be reduced by making measurements with the offset enabled. *4 Add 10 % to the accuracy when measuring 100 V or less. *5 Add 5 % to the accuracy when measuring 100 V or less. *6 When the measured current is limited to 100 nA or more (no condensation) when the humidity is 50 %rh or less, no external disturbance is present such as swinging test leads, and the offset is enabled.

Grounding mode (GND) | Can be switched between Low and Guard. | |||||
Low | GND is connected to the low terminal. Measures the current flowing across the low terminal and chassis (normal applications). | |||||

Filter function | A low-pass filter can be inserted into the ammeter measurement circuit. *2 |
*1 If there is a possibility that the EUT or tools and the like will be grounded or if you are uncertain, do not set GND to Guard. Doing so is extremely dangerous because the ammeter will be shorted and will not be able to measure current. For normal applications, set GND to Low. *2 When the low pass filter is on, a judgment delay of at least 5 seconds and a test time are required.

Start Long | A test starts only when the START switch is held down for at least 1 second. | ||||||
PASS judgment display time (Pass Hold) | Set the time to hold the pass judgment result display (0.05 s to 10.00 s) or hold it until STOP is pressed (Infinity). | ||||||
STOP signal disable (Fail Mode) | It is possible to set the instrument so that fail judgment results and PROTECTION mode cannot be released from a device connected to the SIGNAL I/O connector or REMOTE connector. | ||||||
Key lock | Lock the operation of the keys to prevent changing the settings or overwriting memory or programs by mistake. | ||||||
Protection functions | If a protection function is activated during a test, the output is shut off and the test is stopped immediately.In an LC test, the power supply to the EUT is stopped, and the A and B terminals are opened.Conditions that cause a protection function to be activated are as follows. | ||||||
INTERLOCK | Interlock is activated. | ||||||
POWER SUPPLY | There is an error in the power supply section. | ||||||
OUTPUT ERROR | An output voltage outside of the following range is detected. ACW, DCW, IR test, PD test: ±(10 % of setting + 50 V) EC test: ±(10 % of setting + 2 A) | ||||||
OVER LOAD | An output power or output current outside of the following range is detected. ACW: 550 VA, DCW: 110 W or 50 mA, IR (7200 V test): 110 W or 25 mA, IR (-1000 V test): 2 mA, EC: 240 VA, LC: AC LINE OUT current at approx. 15.7 A or power at 1600 VA. | ||||||
OVER HEAT | The internal temperature of the product is abnormally high. | ||||||
OVER RATING | During a withstanding voltage test, an output current is generated for a length of time that exceeds the output time limit. | ||||||
CAL | The preset calibration period is exceeded. | ||||||
REMOTE | The REMOTE connector is connected or disconnected. | ||||||
SIGNAL I/O | There is a change in the SIGNAL I/O connector’s ENABLE signal. | ||||||
COMMUNICATION | An internal communication error is occurring. | ||||||
OVER RANGE | A value exceeding the maximum value of the measurement range is detected. | ||||||
MEASURE | An error is detected in the LC test measurement check. | ||||||
SHORT | A relay operation error is detected in an LC test. | ||||||
EARTH FAULT | When the grounding mode (GND) is set to Guard, abnormal current flows from the high voltage output of this product to ground. | ||||||
SCAN I/F | While scanning, the interface cable is disconnected. Or, the channel-assigned scanner is not detected. |
