K-D1410Operation and Use Manual for Volume Resistance TesterPlease refer to the attachment for download
Volume resistance testerPlease read the following carefully before using the instrument, otherwise it may cause damage or electric shock to the instrument.
1. ★ Check if the voltage range on the back panel of the instrument is set to 10V and if the current resistance range is set to 104.
2. ★ Turn on the power and zero it (note that the host should not be connected to the shielding box circuit at this time). In the case of an open circuit at both ends of "Rx", zero it to make the ammeter display 0000. Then shut down.
3. ★ Lay the test sample flat in the center of the unprotected electrode, then press the sample with the protective electrode, and insert the protected electrode (unprotected electrode, protective electrode, and protected electrode should be coaxial and confirm that there is no short circuit between the electrodes).
When measuring volume resistance, turn the test button to the Rv side, and when measuring surface resistance, turn the test button to the Rs side,
5. ★ Connect the test cable and connect the host to the shielding box. Set the range to 104 and turn on the power switch button on the back panel of the host. Adjust the voltage button on the back panel of the instrument to the required measurement voltage. (For example, the GBT1692-2008 standard for measuring the insulation resistivity of vulcanized rubber specifies that the measurement should be carried out at a voltage of 500V, so the voltage should be raised to 500V.)
6. ★ Gradually shift the current resistance range button from low gear, hold for 1-2 seconds each time, and observe the displayed number. When the measured resistance is greater than the instrument's measurement range, the resistance meter will display "1". At this time, continue to move the instrument to a higher range position. When the measuring instrument displays a value, it should stop and measure the resistance after 1 minute of electrification time. The current number multiplied by the level is the measured resistance.
7. After the test is completed, first set the range to (104), then set the measured voltage to 10V, and finally turn off the power after setting the test button to the center position. Then proceed to the next test.
8. ★ It should be zeroed when there is an open circuit at both ends of "Rx". Generally, it is not necessary to zero again during the testing process after one zeroing.
9. ★ It is prohibited to short-circuit the "RX" at both ends (direct contact between the three electrodes is not allowed) to avoid damage to the instrument caused by high current impact on the microcurrent amplifier.
10. ★ Do not arbitrarily change the measured voltage during the testing process.
11. ★ Gradually shift from low gear to high gear during measurement.
12. ★ After connecting the power, fingers should not touch the metal parts of the high-voltage line.
13. ★ Do not touch the microcurrent testing terminal during the testing process.
When measuring high resistance, a shielding box should be used to shield the object being measured.
15. ★ It is strictly prohibited to change the voltage range arbitrarily during the testing process and to turn on the host during the power on process.
16. ★ It is strictly prohibited to replace the sample if the current resistance range is not in the 104 range and the voltage is in the 10V range.
