PRODUCT FUNCTION
■A super insulation meter with multiple usage methods
Super insulation meter is a measuring instrument that can be used as a high resistance meter such as IR meter, electrostatic meter, and as a small current meter such as picoammeter, with a wide range of usage methods.
Moreover, HIOKI's self-designed floating circuit can perform stable measurements without being affected by the measurement environment, and is used in production lines to achieve high-speed measurements.
■Deviation 1/60, noise resistance performance 300 times
By combining the new SM floating circuit and three-axis connector, the noise resistance performance is significantly improved.
■Adopting large-diameter three-axis connectors
SM7110 adopts a 16mm large-diameter three-axis connector.
Balancing stability against noise and safety during high-voltage inspections
■The fastest high-speed inspection is 6.4ms
6.4ms=Measurement 4.1+Contact Check 2.3ms
The combination of high-speed inspection and a maximum 50mA pre charging function can achieve high-yield MLCC inspection.
■High performance contact inspection that can also be used in Pian meter mode
Like a picometer, it is equipped with a contact check function that can also be used in measurements using external power sources.
The corresponding range is from 0.1pF to low capacitance determined by the threshold.
You can choose the frequency for inspection, so multiple measuring instruments can also be used for testing on site.
■The output voltage can be set arbitrarily in units of 0.1V, ranging from a minimum of 0.1V to a maximum of 1000V
The output voltage can be set arbitrarily in units of 0.1V, ranging from a minimum of 0.1V to a maximum of 1000V.
[Example of Setting Voltage and Resistance Display Range]
The display range of resistance varies depending on the current range. Attention should be paid when setting the current range to automatic and using resistance display mode.
*Solution for resistance measurement of automotive tires for product application
The national standard GB/T 26277-2010 Tire Resistance Testing Method requires the testing of the resistance of car wheels to prevent static electricity.
I hope to conduct electricity through the wheels and export the accumulated charges from the wheels to the ground.
