Model No. (Order Code)
|SM7110||1 ch, 1000 V|
Note: Measurement leads are not included. Purchase the appropriate lead option for your application separately.
The Hioki SM Series Super Megohm Meters are high resistance and ultra low current inspection devices with a 0.1 fA resolution to offer precise testing on production lines. The SM7110 is designed for use in evaluating and testing the performance of electronic components used in products such as smartphones and hybrid vehicles, and supports measurement voltage output of up to 1000 V.
• 300 times better noise resistance
• Max. 1000 V output : SM7110
• Max. 2 × 10^19 Ω display
• Min. 0.1 fA resolution
• Built-in EXT I/O, RS-232C, GP-IB and USB
1/60 Variability, 300x Noise Resistance
Stability (repeatability) against power supply noise and external noise has improved dramatically due to a combination of new Super Megohm floating circuitry and triaxial connectors.
Variability in normal usage environments is reduced to 1/60 compared to previous models, and to 1/300* in conditions where 50 V noise is applied.
Min. 6.4 ms High-Speed Inspection
6.4 ms = 4.1 ms measurement + 2.3 ms contact check
Achieve high-speed measurement with an inspection time (from TRIG input to INDEX output) of 6.4 ms when contact checks that are essential for mass production inspections are included, and 7.0 ms when comparator measurement is included.
High-Performance Contact Checks
[Low capacity contact checks]
The SM7110/SM7120 is equipped with contact checks that can identify low-capacity capacitors of only a few pF as well as measured objects with a small capacitance.
(Reference value: 0.1 pF to 99.99 pF)
As with battery production lines, select the frequency for contact checks to prevent the minute check signals on site with multiple various measuring instruments from getting crossed.
These two contact checks can also be used in picoammeter mode with an external power supply. These are high-performance contact checks that prevent unnecessary retries and excess detection due to the effects of an external power supply, and that also prevent takt reduction and worsening yield ratio.
