RM3544/RM3548 RESISTANCE METER - 1

RESISTANCE METER Component measuring instruments Easy to use with high precision Resistance Meters for Production Lines and MRO The Resistance Meters RM3544/RM3 544-01/RM3 548 can measure the winding resistance of devices such as motors and transformers, the contact resistance of power contacts (relays and switches), and the DC resistance of fuses, resistors, and substrates such as conductive rubber and sheets. It does so quickly and at a high level of precision using four-terminal measurement. The RM3544/RM3544-01 is well suited to use for adjustment and testing on production lines as well as acceptance inspections, while the RM3548 comprises a portable solution for measuring resistance values ranging in magnitude from microohms to megohms, making it ideal for use in production, main- tenance, repair and operation of large equipment. HIOKI company overview, new products, environmental considerations and other Information are available on our website.

Advanced functionality that's as easy to use as it is easy to understand ,_| # Measurement jacks with guard jack By connecting a probe to the guard jack, you can minimize the effects of external noise on measurements. L #LED COMPARATOR ATTACHMENT (Option) The LED Comparator Attachment indicates judgment results with green and red LEDs, eliminating the need to look at the instrument's screen and increasing work efficiency. Since the lamps do not light up when the measurement leads are open, the attachment can also be used to verify the connection status. # Simple control over basic settings...
