SWR/POWER/MODULATION METE R
Models : TM-3000/TM-2000 INSTRUCTION MANUAL
INTRODUCTION
TM-3000/2000 is a compact test meter to indicate the condition of 1.6-60 MHz / 26 -30 MHz antenna system
and transmitter with an impedance of 50 ohm. With TM series you can measure SWR, relative output power of the
transmitter and AM modulation.

Summary

Introduction to SWR;Power;Modulation Meter

Meter Installation and Operation

Installation Procedure

Connects the SWR meter to the transmitter and DC power supply.

Forward Power Measurement

Sets the FUNCTION switch to FWD and reads the power scale.

Reversed Power Measurement

Measures reverse power on the coaxial cable between transceiver and antenna.

VSWR Measurement

Sets FUNCTION to SWR, calibrates, and adjusts for full scale deflection.

AM Modulation Level Measurement

Sets FUNCTION to MOD, calibrates, and adjusts for full scale deflection.

Operating Cautions

Advises against vibration, reverse connection, tampering, and extreme conditions.
