The Swain Automer™ DC Current Clamp Meter is a test meter for corrosion detection that features auto ranging and auto zeroing. MER stands for Magnetic Error Reduction.
Our 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 AutoMER and MER® Meters.
- 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.
- AutoMER 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
(direction of flow) of measured current is shown both on the LCD
meter and also at the output terminals.
- AutoMER 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
- External Battery
- 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.
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.
