轻松便携，易用易懂：维护保养/大型设备的检查等最适用的外形，可使用标配挂绳，套在脖子上将电阻计悬挂于身体前方，双手持探头进行测量。电源为8节5号干电池，普通状态测量可使用约10小时。(根据测量条件不同使用时间有所变化),自动保持，自动存储只要探头接触被测物，就能自动保持/记录，配备自动存储功能。无需按钮操作，等数值稳定后，会自动记录。触手可及的比较器指示灯比较器指示灯安装于探头附近，如此一来，即便在测量中也能对结果判断一目了然。OFF SET电压补偿(OVC)功能不同金属的连接部分会产生热电动势。当热电动势过大时，会引起测量误差。OFF SET电压补偿功能(OVC)可减轻热电动势的影响，更高精度的进行测量。长度换算功能设置每1m的电阻值时，电阻值可换算为长度。此功能在线缆的库存管理，PCB的焊盘长度推测时十分便利。无需调零无需调零即可达到规定精度。接通电源，即可测量。耐压性能大幅提高过电压最大可保护到 70V。可防止直接接入充电中的电荷或受电感的逆变功率影响所引起的故障。通过USB连接取得所记录的测量数据通过USB线缆与电脑连接，读取主机中保存的测量数据。RM3548支持USB大容量存储级别(读取专用)，无需在电脑端另外安装驱动软件。温度上升试验中便利的温度换算功能和间隔测量：从所测量到的电阻值和周围温度，可换算出上升温度(Δt)并进行显示。特别是在电机马达或变压器评估时，需要确认通电后的最高上升温度。使用间隔测量功能，可从测量开始时以指定的间隔进行测量。因为主机具备记录功能，对于推算最高温度较为容易。温度换算功能，无法与温度补偿功能、长度换算功能同时使用。在电机马达，变压器完全与室温融合的情况下，测量通电前的电阻值(R1)，以及周围温度(t1)，将数值输入主机将测试线从被测物上取下通电OFF后，再给被测物接上测试线，使用间隔存储功能测量并记录每隔一段时间的温度上升值(Δt1～Δtn)。结合测得温度数据(Δt1～Δtn)、推算最高温度上升值(Δt)。测量精度：电阻测量精度；精度保证条件温湿度范围23℃±5℃，80%rh以下(不凝结)；0~18，28~40℃时，需要加算温度系数±(测量精度的1/10)/℃，RM3548精度：±(%rdg.＋%f.s.)，(f.s.＝30,000dgt.来计算，0.010%f.s.＝3dgt.)，温度测量精度，温度传感器Z2002(用于RM3548)。温度传感器Z2002与RM3548组合精度。Easily portable, easy to use and understand: the most suitable shape for maintenance/inspection of large equipment, etc. You can use the standard lanyard, put it around your neck to hang the resistance meter in front of your body, and hold the probe with both hands to take measurements. The power supply is 8 x 5 dry cell batteries, which can be used for about 10 hours of measurement under normal conditions. (According to the measurement conditions of different use time varies), automatic hold, automatic storage as long as the probe contact with the measured object, can be automatically held/recorded, equipped with automatic storage function. No need for button operation, it will automatically record when the value stabilizes. Comparator indicator within easy reachThe comparator indicator is mounted near the probe, so you can judge the result at a glance, even in the middle of a measurement.OFF SET Voltage Compensation (OVC) FunctionThe thermal electromotive force is generated in the part where different metals are connected. The OFF SET Voltage Compensation (OVC) function mitigates the effects of the thermo-electric potential and enables more accurate measurements. LENGTH CONVERSION FUNCTION When setting the resistance value per 1m, the resistance value can be converted to length. This function is convenient for cable inventory management and PCB pad length estimation. No Zeroing Required The accuracy of the measurement can be achieved without zeroing. Measurement can be performed by turning on the power. The overvoltage resistance has been greatly improved, and overvoltage protection up to 70 V is available to prevent malfunctions caused by direct access to charging charges or by the inductive inverter power. Measurement data recorded via USB connectionConnect to a PC via USB cable to read measurement data stored in the host computer.The RM3548 supports USB mass storage level (for reading), eliminating the need to install separate driver software on the PC. Convenient Temperature Conversion Function and Interval Measurement in Temperature Rise Test: From the measured resistance value and surrounding temperature, the rise temperature (Δt) can be converted and displayed. Especially when evaluating electric motors or transformers, it is necessary to confirm the maximum rise temperature after energization. Using the interval measurement function, measurements can be taken at specified intervals from the start of the measurement. Since the main unit has a recording function, it is easy to deduce the maximum temperature. The temperature conversion function cannot be used in conjunction with the temperature compensation function and the length conversion function. With the motor and transformer fully integrated into the room temperature, measure the resistance value (R1) before energizing the motor and transformer, and the ambient temperature (t1), input the values into the main unit, remove the test lead from the DUT, energize the DUT, connect the test lead to the DUT, and then use the interval memory function to measure and record the temperature rise (Δt1 to Δtn) at intervals. Combine the measured temperature data (Δt1 to Δtn) with the maximum temperature rise value (Δt). Measurement accuracy: resistance measurement accuracy; accuracy guarantee conditions temperature and humidity range of 23 ℃ ± 5 ℃, 80% rh or less (non-condensing); 0 ~ 18, 28 ~ 40 ℃, you need to add the temperature coefficient ± (1/10 of the measurement accuracy) / ℃, RM3548 accuracy: ± (% rdg. + % f.s.), (f.s. = 30,000dgt. to calculate, 0.010% f .s. = 3 dgt.), temperature measurement accuracy, temperature sensor Z2002 (for RM3548).
