Two Z3003 Multiplexer Units can be installed on the RM3545-02.
Number of locations that can be measured
Benefits of using the Multiplexer Unit
• Since each channel’s pins can be combined freely, it is possible to measure a variety of
measurement targets with the minimum amount of wiring.
See: "8.7 Example Connections and Settings"(p.167)
Example: 3-phase motor with Δ wiring or Y wiring
Series elements such as a network resistor
Independent elements
• Different measurement conditions can be set for each channel.
See: "8.3 Multiplexer Settings"(p.148)
• Batch zero-adjustment can be performed for the desired channels.
See: "8.5 Zero Adjustment (When a Multiplexer Unit Has Been Installed)"(p.163)
• Judgments can be made using measured values as references.
See: "Setting Basic Measurement Conditions and Total Judgment Conditions for Individual Chan-
nels" (p.156)
• Up to 42 channels can be registered.
• Up to eight setting panels (panel number: 31 to 38) can be saved, apart from measure-
ment conditions for which the multiplexer is not used (when using the measurement ter-
minals on the front of the instrument).
• You can choose from the following three scan methods according to your application:
(1) Scan function: OFF
(2) Scan function: Step
(3) Scan function: Auto
