专业维修安捷伦 8163B 光波万用表,其常见的故障及原因分析如下
故障点:指针摆动不正常
原因分析:可能是由于机械平衡不好,指针与外壳玻璃或表盘相摩擦;或者表头线断开、分流电阻断开;游丝绞住或不规则;支撑部位卡死等。
故障点:电阻挡测量不准确或不稳定
原因分析:电池电能耗尽或接触不良;串联电阻值变化;表笔与插头接触不良;转换开关或调零电位器接触不良等。
故障点:某量程不工作或测量误差大
原因分析:对应量程的串联电阻断开、烧断或电阻值变化;转换开关接触不良;分流电阻断路或短路;电池电量不足等。
故障点:直流电压挡不指示或测量误差大
原因分析:测量电压部分开关公用连接线脱焊;转换开关接触不良;表笔插头与万用表接触不良;最小量程挡附加电阻断线等。

Professional maintenance of Agilent 8163B light wave multimeter, its common faults and causes are analyzed as follows
Fault: The pointer does not swing properly
Cause analysis: It may be due to poor mechanical balance, the pointer and the shell glass or dial phase friction; Or the meter head line is disconnected, the shunt resistance is disconnected; A hairspring is twisted or irregular; The support part is stuck.
Fault point: Electrical barrier measurement is inaccurate or unstable
Cause analysis: battery power depletion or poor contact; Series resistance value change; Poor contact between marker and plug; The transfer switch or zero potentiometer is in poor contact.
Fault point: a range does not work or the measurement error is large
Cause analysis: the series resistance of the corresponding range is disconnected, burned off or the resistance value changes; The transfer switch is in poor contact; Shunt resistance open or short circuit; Low battery power, etc.
Fault point: DC voltage stop does not indicate or the measurement error is large
Cause analysis: The measuring voltage part of the switch common connection line out of welding; The transfer switch is in poor contact; The pen plug is in poor contact with the multimeter; Minimum range stop additional resistance break line, etc.
Fault: The AC measurement function is abnormal
Cause analysis: It may involve poor contact between the plug and socket of the multimeter. The transfer switch contact is poor; Rectifier full bridge or rectifier diode short circuit, open circuit and other problems.
