2011 Portable DC Ammeters and Voltmeters
・Permanent moving coil type
・Magnetic circuit preventing external magnetic field effect
・Temperature compensation circuit is provided
Models 2011 are moving coil type instruments using a taut-band suspension system.
The suspension system providesexcellent reproducibility without friction, and strong resistance to shock impact.
These precision instruments combine a magnetic circuit (sandwich mechanism) that blocks the effects of external magnetic fields, and a superior temperature compensation circuit.
Features
Taut-band suspension system eliminates friction and provides strong resistance to shock impact.
Stable performance ensures that changes over time are negligible.
Quick response and easy-to-read scale
Superior temperature compensation circuit reduces external temperature effects.
Magnetic circuit (sandwich mechanism) reduces the effects of external magnetic fields.

Scale
2011 41 50 mV instrument and 2011 42 1 mA instrument
The scale for the 50 mV instrument has 100 and 150 divisions. A 50 mV current
transformer may be combined with any rated current instrument to read
measurements through a simple conversion process. DC scales (single scale or dual
scale) are also available by special order.
