SWAIN METER电流表Auto MER介绍
Swain Auto MER直流电流钳表是一种用于腐蚀检测的测试仪表，具有自动量程和自动归零功能。 MER™ 代表减少磁误差。
Pelican外壳设计防水，并使用防尘、军用风格、Cannon 连接器。数据记录输出插孔是所有 Auto MER和MER仪表的标准项目。
特征：
可选配外部电源。
测量范围是自动选择的——通常是 2、20或200 A，在输入电流变化的几秒钟内。零位也是自动和精确设置的。
Auto MER型直流电流钳通常更准确。它们的构造可显着减少由于传输线管道中的剩磁或车辆中的磁铁引起的零偏移误差。与可比较的标准 Swain Meters 相比，优点是二或三比一。
测量电流的极性（流向）显示在LCD仪表和输出端子上。
Auto MER完全便携，可使用50小时。显示电池和“低电量”图标。
在“自动”中，量程选择、调零和电池关闭都是自动的。
在“手动”中，选择范围并手动设置归零。电池电量保持开启。
外接电池是可选的。
分辨率：0-2Amp范围为1mA，0-20Amp范围为20mA，0-200Amp范围为100mA分辨率。
内径为 24" 至 60" 的夹具具有 10 mA 的分辨率。
精度为 ±1% 读数，±3位，由于磁性造成的±零偏移。LCD仪表有3 ½位数字和 ½”高数字。
在任何范围内，记录仪的输出在满量程输入时为±2 V。超量程可用。交流输入电流在10 A rms – 60 Hz输入时被拒绝变化小于5 mA。
The Swain Auto MER DC Current Clamp Meter is a test meter for corrosion detection that features auto ranging and auto zeroing. MER stands for Magnetic Error Reduction.
Pelican brand case design is water resistant and uses dust proof, military style, Cannon Connectors. Data logging output jacks are a standard item on all Auto MER and MER Meters.
Features:
Optional external power source available.
Measurement range is selected automatically — typically 2, 20, or 200 A., within seconds of a change of input current. Zero is also automatically and precisely set.
Auto MER model DC Amp Current Clips are generally more accurate. They are constructed to substantially reduce zero offset error due to residual magnetism in transmission line pipe, or magnets in vehicles. The benefit is usually two or three to one over comparable standard Swain Meters.
Polarity (direction of flow) of measured current is shown both on the LCD meter and also at the output terminals.
Auto MER is fully portable, with 50 hr. battery and “Low Batt” icon.
In “Auto”, Range selection, Zero adjustment, and also battery OFF are automatic.
In “Manual”, Range is selected and Zero is set by hand. Battery power stays on.
External Battery is optional.
Resolution: 0-2Amp range is 1mA, Zero to 20Amp range is 20mA, Zero to 200Amp range is 100mA MAX resolution.
Clamps with 24″ to 60″ inside diameter have 10 mA max. resolution.
Accuracy is ±1% reading, ±3 digits, ± zero offset due to magnetism. The LCD meter has 3½ digits with ½” high numerals.
Output for a recorder is ±2 V at full scale input on any range. Overrange is available. AC input current is rejected to less than 5 mA change with 10 A rms – 60 Hz input.
SWAIN METER传感器MER2介绍
MER2 DC Amp Clips和Clamps是“Swain 传感器”，可在正常操作期间精确检测磁化导体上流动的直流电流的大小和方向，而不会中断电路。用于地面和海底阴极保护的 Swain 便携式直流夹的直径为2英寸到10英寸。Swain夹具是两件式传感器，直径从6英寸到60英寸不等。可根据要求制造更大的夹具。夹具以4件部分制造，尺寸大于60英寸。
MER2型（双倍磁误差减少）直流电流钳通常更准确地用于使用非接触式传感器测量直流电。它们的构造是为了减少由于钢管、钢筋附近或汽车和卡车电池附近常见的不均匀磁场引起的误差。零偏移误差通常小于可比标准Swain Meters的四分之一。
典型精度为± 1% 读数、± 3 位、± He。用户友好的3 1/2 位LCD仪表，极性和1/2"高数字。（他是传感器对地球磁场的零偏移灵敏度。除非钢靠近并扭曲它，否则地球磁场是均匀的。附近有强磁铁也可能导致零偏移。）
防止300 A过载
MER2 DC Amp Clips and Clamps are “Swain Sensors” which precisely detect the magnitude and direction of direct current flowing on magnetized conductors during normal operation without interrupting the circuit. Swain portable DC amp clips for cathodic protection above ground and sub sea are manufactured from 2″ to 10″ in diameter. Swain clamps are two piece sensors manufactured from 6″ to 60″ in diameter. Larger clamps may be built upon request.Clamps are manufactured in 4 piece sections for sizes greater than 60″.
MER2 (Magnetic Error Reduction doubled) type DC Amp Clips are generally more accurate for measuring direct current with a non-contact sensor. They are constructed to reduce errors due to non-uniform magnetic fields common on steel pipe, near rebar, or near the battery in cars and trucks. Zero offset error is generally less than one quarter that of comparable standard Swain Meters.
Typical accuracy is ± 1% reading, ± 3 digits, ± He. User friendly 31/2 digit LCD meter with polarity & 1/2″ high numerals.(He is zero offset sensitivity of the sensor to the earth’s magnetic field. The earth field is uniform unless steel is close and distorts it. A strong magnet nearby can also cause zero offset.)
Protected from 300 A overload.
