About This Product

■Measurement and diagnosis of ground wire resistance and power cord resistance of ME equipment・Power cord resistance diagnosis
・Grounding resistance diagnosis for equipment whose power cord cannot be removed
・3P table tap resistance diagnosis

■Why is it necessary to measure the resistance of the power cord?・Poor contact or disconnection may occur due to insertion/removal, twisting, or deterioration over time.
・If the resistance value of the ground line is large, there is a risk of electric shock.

JST T0601 (corresponding international standard IEC 6060-1)
<Medical electrical equipment - Part 1: Excerpt from general safety requirements> Excerpt

<Impedance and current carrying capacity>
For ME equipment equipped with an equipment power socket, the protective grounding blade of the equipment power socket
The impedance to all protective earthed parts shall not exceed 0.1Ω.
↓
In summary, the resistance of the ground line should not exceed 0.1Ω.

The purpose of this is to prevent microshock (tolerance: 0.01mA*)
*1/10 of 0.1mA that causes ventricular fibrillation when in direct contact with the heart

100 power cables actually used at a medical institution
As a result of testing the grounding wire resistance value, 60% of the cables had a resistance of 0.11Ω or more.
There is also data.

■Advantages of using a power cable checkerAt some medical institutions, the number of medical devices returned each day ranges from 30 to 50.
Abnormalities in appearance are easy to notice, but the resistance value of the power cord needs to be measured.
Attempting to measure this using a commercially available tester would require a great deal of effort.

Even if you try to measure the resistance value with a tester, the following problems will occur.
- Unstable contact between probe and terminal
・It is necessary to measure the ground wire E, power wire L, and power wire N three times in total.
- Inaccurate ground wire resistance measurement
・It takes time from preparation to completion of measurement
・Can only be measured by someone with specialized knowledge

By using a power cable checker
Problems with tester measurement can be solved at once.
・Measurements can be made in a stable position due to the cable plug-in type product design.
・With the cable plug-in type, two power wires and one ground wire can be measured at one time.
・Accurately measure ground wire resistance by adopting a high-precision 4-terminal measurement method
・Resistance measurement completed in about 10 seconds
- Anyone can use it, just plug in the cable and press the measurement switch.
- Battery operated so you can use it anywhere
