12681, 444-2產(chǎn)品概述

Low Voltage Micro-Ohmmeter

Model 444 measures resistances from 1 micro-ohm to 20 ohms, in either AC pulse or DC polarity switching measurement modes. Extremely small test voltage (100 μV max.) prevents "punching through" contamination or corrosion. The 444 features a 41/2 digit LCD display and a user adjustable low-resistance alarm and operates at 85-250 VAC. Ideal for testing antenna grounding systems, conductive coatings, high power fuses, or aircraft skin bonding. Comes with test leads and NiCad battery pack for field use.

This ohmmeter measures using an extremely small test voltage 100 μV (Max.) and a four wire measurement technique. The resistance reading is indicated on a 4-1/2 digit LCD display using one of two measuring modes, an automatic AC measurement mode or a manu
