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.

Notes
1. 201131 and 201132 are equivalent to Class 1.0.
2. For ranges higher than 30 A, externally connect a shunt 2215-2217 (page 10) to the 50 mV terminal on 2011 41 (50 mV instrument) or 2012, 2011 41 (50 mV instrument) and 2012 both come with aset of shunt cables (two 1.5-meter cables with 0.025 Ω resistance). Different cables may be used if the cable resistance is 0.1 Ω or less.
