Auto test |
Auto execution by combining ACW, DCW, IR, and EC. For LC, a combination is possible only using TC, PCC, and Patient. |
Test condition memory |
Setup Memory |
Up to 51 test conditions (ACW, DCW, IR, EC, PD, LC) can be saved. |
Program memory |
Up to 100 program (ACW, DCW, IR, EC, PD) combinations, each containing 100 steps, can be saved. |
Program memory (LC) |
Up to 100 program (TC, PCC, Patient) combinations, each containing 100 steps, can be saved. |
Test result memory |
Records up to 1000 latest test result of independent tests and auto tests. These are cleared when the power is turned off. Test results can be saved in CSV format to a USB memory device. |
System clock |
|
For recording the calibration time and test times |
Recordable time |
Up to year 2038 |
Calibration period setting |
Displays a warning at power-on when the specified period passes. Select whether to activate a protection function or only display a warning in the display area when a warning occurs. |
Display of measured values |
|
Maximum and minimum measurements can be displayed. |
Normal |
Displays measurements during a test. Maximum and minimum values are not held. |
Maximum and minimum value display |
Displays the maximum current measurement for withstanding voltage (ACW/DCW) tests, the minimum resistance measurement for insulation resistance (IR) tests, the resistance measurement or voltage measurement for earth continuity (EC) tests. |
Test start method |
Double Action |
When you press STOP, “READY” is shown for 0.5 seconds. A test starts only when you press START within this period. |
Momentary |
Tests are only executed while the START switch is held down. |
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. |
