TOS9300_Earth Continuity Test-Judgment function
| Item | TOS9302 | TOS9303 | TOS9303LC |
|---|
| Behavior based on judgment | | Judgment based on resistance or sensing voltage can be selected. The output is shut off when a judgment is made. Buzzer volume level can be set in the range of 0 (OFF) to 10 for pass and fail separately. In an auto test, the buzzer is valid only for the judgment that takes place at the end of the program. |
|---|
| UPPER FAIL | Judgment method | UPPER FAIL results when a resistance greater than or equal to the Upper limit is detected or when a sensing voltage is detected. Judgment is not made during a contact check. |
|---|
| Display | “U-FAIL” is displayed. |
|---|
| Buzzer | On |
|---|
| SIGNAL I/O | The U-FAIL signal is generated continuously until a STOP signal is received. |
|---|
| LOWER FAIL | Judgment method | LOWER FAIL results when a resistance less than or equal to the lower limit (Lower) is detected or when a sensing voltage is detected. |
|---|
| Display | “L-FAIL” is displayed. |
|---|
| Buzzer | On |
|---|
| SIGNAL I/O | The L-FAIL signal is generated continuously until a STOP signal is received. |
|---|
| PASS | Judgment method | PASS judgment is made if U-FAIL or L-FAIL has not occurred when the test time elapses. |
|---|
| Display | “PASS” is displayed. |
|---|
| Buzzer | On (fixed to 50 ms) |
|---|
| SIGNAL I/O | The PASS signal is generated for the length of time specified by the Pass Hold setting. If Pass Hold is set to Infinity, the PASS signal is generated continuously until a STOP signal is received. |
|---|
| Resistance judgment | Upper limit setting range | 0.0001 Ω to 10.0000 Ω |
|---|
| Lower limit setting range | 0.0000 Ω to 9.9999 Ω |
|---|
| Judgment accuracy | ±(2 % of setting + 3 mΩ) |
|---|
| Voltage judgment | Upper limit setting range | 0.001 V to 5.000 V AC/DC |
|---|
| Lower limit setting range | 0.000 V to 4.999 V AC/DC |
|---|
| Judgment accuracy | ±(2 % of setting + 0.05 V) |
|---|
| Calibration | Calibrated using a pure resistive load (with the rms of a sine wave for AC) |
|---|
| Contact check function | Checks that current flows through the test leads and then starts the test. (OFF setting available) |
