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 HIOKI ST5520 Insulation Resistance TesterPerformance characteristics
Implemented 'high-speed' insulation resistance inspection
50ms high-speed judgment
Quickly release residual voltage
Set the test voltage value arbitrarily (25-1000V (1V resolution) setting)
Contact inspection function (to prevent misjudgment caused by poor contact)
Short circuit inspection function (preventing defective products from entering the market)
The host cannot measure separately. Please purchase a separate testing line according to the measurement purpose.
Realize "fast" insulation resistance inspection
The insulation resistance tester ST5520 is a product that meets the fast-paced requirements of production lines.
Completed the inspection at a speed of 50ms. Compared with our previous models, the speed has increased by nearly 700ms. (※ The inspection results of the tested object with a waveform of 9M Ω and 10pF.). ）
High speed automatic discharge function
The discharge time after inspection has been significantly reduced compared to previous models. Under the same conditions, an improvement of 990ms in working hours can also be achieved.
Two types of contact checks
There are two types of contact inspection functions when connecting with 4 terminals and 2 terminals.
Improving inspection quality through micro short circuit detection
Accurately identify adverse phenomena such as micro short circuits caused by high voltage leading to equipment burnout through low voltage inspection.
Probe with switch (optional)
It can be operated directly with a handheld probe to achieve safe and simple measurements.
Japanese HIOKI ST5520 Insulation Resistance TesterBasic parameters
Test project Insulation resistance (DC voltage application method)
Test voltage/measurement range (manual/automatic)
25 V ≦ V < 100 V (2.000/20.00/200.0 MΩ),
100 V ≦ V < 500 V (2.000/20.00/200.0/2000 MΩ),
500 V ≦ V ≦ 1000 V (2.000/20.00/200.0/4000/9990 MΩ)
Basic accuracy ±2 % rdg. ±5 dgt.
25 V ≦ V < 100 V [0～20 MΩ],
100 V ≦ V < 500 V [0～20 MΩ],
500 V ≦ V ≦ 1000 V [0～200 MΩ]
test speed FAST: 30ms/time, SLOW: 500ms/time (switching)
display LCD (with a lifespan of 100000 hours), 4-stage backlight
Storage function
Save contents: rated measurement voltage, upper and lower limits of comparator, test mode, buzzer sound during judgment, test time, response time, resistance range, measurement speed
Storage capacity: up to 10 sets (can be saved/read)
Test mode Continuous mode, PASS STOP mode, FAIL STOP mode, and forced end judgment mode (switching)
Compare settings UPPER-FAIL: Measurement value ≥ upper limit value
PASS: Upper limit value>measured value>lower limit value
LOWER-FAIL: Measurement value ≤ lower limit value
Judgment processing Beep sound, LED lights for PASS/U.FAIL/L.FAIL are on, and the lights for U.FAIL/L.FAIL are on at the same time when UL_LAIL is on. EXT. I/O output, and the judgment result is obtained through RS-232C
Test time timer 0.045 s to 999.999 s (0.001 s resolution), the time from applying voltage to determining whether it is qualified or not
Response time timer After the experiment begins, it is prohibited to set the comparator to determine the action time between 0.005 s and 999.999 s (0.001 s resolution)
Analog Output DC +4 V f.s.
interface RS-232C (standard), external I/O (input for external controller, output of judgment result), BCD output (ST5520-01 only)
power supply AC100 V ～ 240 V，50/60Hz， Maximum 25VA
Volume and weight 215W×80H×166Dmm，1.1kg
attachment User manual x 1, power cord x 1, EXT.I/O connector x 1, connector cover x 1
