地质部地球物理探矿局修造所在总路线的鼓舞下,结合野外物探队的迫切需要,于1958年上半年试制成了多种新的物探仪器,它们是仿苏ЗCK-1型电子电位自动补偿仪,仿苏ИЖ型岩脉仪,仿苏水电阻仪,仿瑞典M-1型万能磁力仪,和仿苏KΦ型井径仪等。ЗCK-1型电子电位补偿仪按照自动补偿电路原理制成。被测电位差和电子线路中一个电压降十分近似相等可以自动完全补偿的特性,使仪器具有很高的灵敏度,可测50-100微伏的微小电位差。仪器具有较低的测量误差,在用0-10毫伏刻度时平均误差不超过1.5%,在用0-3毫伏及0-1毫伏刻度时平均不超过
Inspired by the general line of the Geophysical Prospecting Bureau of the Ministry of Geology, in conjunction with the urgent need of the field geophysical team, a number of new geophysical prospecting equipment were trial-produced in the first half of 1958 and they were imitation SU ЗCK-1 automatic potentiometers , Imitation Su ИЖ-type dichroism meter, imitation Su water resistance meter, imitation Sweden M-1 universal magnetometer, and imitation Su KΦ diameter caliper and so on. ЗCK-1-type electronic potentiometer in accordance with the automatic compensation circuit is made. The measured potential difference and electronic circuit in a voltage drop is approximately equal to automatically fully compensate for the characteristics of the instrument has a high sensitivity, measurable 50-100 microvolts tiny potential difference. The instrument has a lower measurement error, with an average error of not more than 1.5% at a 0-10 millivolt scale, on average no more than 0-3 millivolts and a 0-1 millivolt scale
