2012-00 Portable DC Ammeters and Voltmeters

2012-00 Portable DC Ammeters and Voltmeters
・Permanent moving coil type
・Magnetic circuit preventing external magnetic field effect
・Temperature compensation circuit is provided

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.
