Overview
1.1 Product Overview and Features
This instrument is an insulation resistance meter containing a highly sensitive ammeter and a low-
noise voltage supply.
Employing the triaxial BNC connector enables the instrument to measure high resistance such as
resistance of insulators with no inuence of exogenous noise.
The maximum measurement voltages of Model SM7120 and Model SM7110 are 2000 V and 1000 V,
respectively.
Stable measurements for a variety of items
• The triaxial BNC connector is used to have external noise resistant structures.
• The maximum measurement voltage is 2000 V, so various objects can be simply measured with
a single instrument.
• The instrument has a wide measuring range. (Depends on applied voltage)
• Resistance measuring range: (p. 142
)
; Current measuring range: 0.1 fA to 2 mA
• Because temperature and humidity can be measured simultaneously, change in resistance can
be checked against the change in temperature and humidity.
• The contact check function enables you to perform stable measurements even when a voltage
applied to measured objects is 2000 V or higher.
Suitable for production lines
• High-speed measurement; it takes only 6.4 ms from input of a trigger to output of the INDEX
signal.
• The frequency change function of contact check reduces interference with other devices in the
production line.
• It is not necessary to correct cable length even when changing production line construction
because the instrument automatically corrects the cable length of contact check.
• Because you can check the control status with the command monitor function and the external
I/O monitor function, you can quickly construct a production line.
• Because the external I/O is compatible with both NPN and PNP types, you can immediately use it
on your production line.
What can be measured
• Insulation resistance between capacitor terminals
• Insulation resistance between a battery terminal and a case
• Insulation resistance between coils of common mode lters
• Checking breakdown voltage
• Surface resistivity and volume resistivity of lm, etc.
• Insulation resistance of liquid sample
