Purpose ZX127 type high-resistance resistance box is suitable for factories, schools and scientific research units to be used in AC and DC circuits or electronic circuits, as precision adjustable impedance components, bridge arm components, or for medium and high resistance electric bridges, medium and low insulation resistance testers, etc. The instrument is used for machine calibration. Second, the main technical indicators 1. When the 4 read-only counters of this product are in the minimum gear, the resistance is 0Ω. 2. The minimum step value of this product is 10kΩ. 3. The adjustment range of this resistance box is 0~121.10MΩ. 4. The reference temperature and nominal temperature of the resistance box should meet the following requirements: Reference range: 20±0.5℃ Nominal range: 20±5℃ 5. The reference relative humidity and nominal relative humidity range of the resistance box should meet the regulations: Reference range: 40%~60% Nominal range: 25%~75% Three, matters needing attention 1. Before using the resistance box, the switches should be rotated several times to make the instrument contact stable. 2. The resistance box must not exceed the nominal power when in use. 3. The resistance box should be stored in a shielded environment with an ambient temperature of 10-30°C, a relative temperature not exceeding 75%, no corrosive gas in the air, and the instrument should not be in contact with bad impurities; avoid direct sunlight To the instrument. 4. Supplementary Provisions 1. Under the condition that the user abides by the usage and storage rules, within 1 year from the date of delivery verification, if there is a quality problem in the resistance box, we will repair or replace the user for free; and promise to provide life-long maintenance services. 2.
