Commentary
DC volt meter kit of measuring instrument series.
By using a high-performance operational amplifier, etc., it has a high input resistance of 1M Ω in any measurement range, eliminating measurement errors in low-voltage measurement that are often seen in testers.
In addition, it is possible to measure the voltage without disturbing the operating state even when the impedance of a vacuum tube circuit is high.
The range allocation is divided into five ranges from the minimum voltage range of 0.1 V to the maximum voltage range of 100 V. The range allocation is made especially suitable for the voltage measurement of transistor devices by an attenuator using a precision grade resistor.
Taking advantage of the advantages of an electronic voltage system, it has functions such as 0 adjustment which can set the reference point of meter indication arbitrarily, which cannot be seen by a tester.
In combination with M-2V, etc., only the meter part is used by the meter selector switch, so it can be used as a high-sensitivity volt meter for both AC/DC.
The voltage scale is a 10-dB step scale used for general millibars. It is compatible with a range switch of M-2V. In addition, it is equipped with a logarithmic scale (dB) indispensable for AC measurement. There are two types of scale, dBm value and full scale 0 dB.
Can also be used as a strain rate meter by combining with M-3G.
