Product details
Professional Instrument Equipment and Testing Solution Supplier - JETYOO Industrial&Jianyou (Shanghai) Measuring Instrument Co., LtdFounded in 2011 by Jian JET, a product technical support engineer for Agilent (now known as KEYSIGHT), and Rong YOO, a product technical support engineer for KEITHLEY (now known as Tektronix)Characterized by technological applicationsThe agency trading company,Focused on the industrial testing industry for 16 yearsAiming to break through the old and establish the new! Fill the gap of most imported instrument and equipment manufacturers only setting up sales points in China, but with weak or no technical support, and agent distributors only specialize in sales, not professional in pre-sales technical Q&A/testing plans, and not professional in after-sales training/maintenance calibration. oursTechnical salesAll of them have a bachelor's degree or above, and have more than 10 years of experience in the testing industry. With our advanced and unique business philosophy of "relying on technology! Selling instruments!", we specialize in providing instrument equipment, testing solutions, technical training, maintenance and measurement services for Chinese users, serving the industryA company with technical engineersA technology oriented comprehensive service provider for instruments and equipment.
Japanese Japanese Grounding Resistance Tester HIOKI3157-01Application Cases
Conductivity test of protective grounding wire for commercial air conditioning
Confirmation of grounding wire for work machine
Protection and conductivity test of medical and testing equipment imported from abroad
Safety testing of recycled products for OA equipment
Grounding wire inspection for entertainment equipment
AED safety testing and maintenance
Protective grounding tester required in standard certification
What is the protective conductivity test?
The AC grounding resistance tester 3157 measures low resistance using the AC 4-terminal measurement method, which measures the voltage drop when a high AC voltage (up to 31.0A) flows through the tested object.
Measurement of protective conduction resistance of electrical equipment
Grounding connection inspection of electrical work equipment and distribution cabinets
Inspection of protective grounding and equipotential grounding engineering for medical equipment
Evaluation of Contact State with High Current Flow
Safety signs applicable to the following electrical equipment
Using standard examples IEC60065 IEC60335-1 IEC60601-1 IEC60950-1 IEC61010-1 JIS T1022:2006 JIS C1010-1 Electrical Appliance Safety Law UL (Various Standards for Use), etc
Simply implement protective conductivity testing that complies with various safety standards and regulations in Japan and abroad. Used for measuring the protective conductivity resistance of medical electrical equipment and general electrical equipment. Grounding inspection during the installation of electrical work equipment and distribution boards. Inspection and evaluation of protective grounding and equipotential grounding engineering for medical equipment to assess the contact state of high current flow
Can be equipped with a constant current feedback control method that does not vary with load changes
After confirming the connection of the tested device, the software for applying current is started
The host cannot measure separately. Please purchase option 9296 current probe (2) or 1 each of 9296 current probe and 9297 current external probe according to the corresponding measurement purpose.
