ZX90~ZX99 Variable Decade Resistance Box
Introduction
Type ZX90~ZX99 DC resistor is a multiple - valued resistor, formed by decade resistor groups in series. The resistance between both fasteners can be changed with the position of the switch brush contact.
The resistor is miniature and portable. The switches are fully enclosed, no .need to clean, low pressure of contact , long life time and less variations. The stand of the resistor is made of plastic so that the insulation resistance is high. The readings of resistance on the panel is lined up, and can be read forthright and clearly. The resistance elements are all wound noninductively with enameled manganin wire, and go through strict technical process, in this way, the resistor has high stability and can be used in any position.

Notice and Maintenance
During using the resistor, the applied power should be within nominal value.
Before using the resistor, all switches should be rotated for several times so as to be in good contact.
The resistor should be kept in a room v/ithout corrosive gases and harmful impurity substance, in which the enviremental temperature is 5〜35°C and the relative humidity is 25%〜80%. It should also be out of the sun.
