Page 3: Special Notes
MM-601B 1. Special Notes (1) Safety Precautions CAUTION Prior to use, read these “Safety Indicates operations and practices that may Precautions” carefully to gain a full result in personal injury or damage to the understanding of the proper method of equipment if not correctly followed.
Page 4 Do not use a damaged connecting cable or plug. A damaged cable or a plug can cause electric shock, short circuits and fire. If any part needs to be repaired or replaced, consult Miyachi or your distributor. Stop the operation if any trouble occurs.
Page 5 MM-601B CAUTION Remove any dust on the AC adapter and connect it securely. Dust and improper connection of the AC adapter may result in heat generation and fire. Hold the plug when plugging or unplugging the AC adapter. Do NOT pull on the power cord, as this may damage it, resulting in electric shock or fire.
Page 6: Precautions For Handling
MM-601B (2) Precautions for Handling • Do not install the device in the following locations: Damp areas (where the humidity is above 90%), areas exposed to large amounts of vibration or shock, dusty areas, areas near a high noise source,...
Page 7 MM-601B • Use only the included or specified chargers. • Do not charge for more than 48 hours. • Do not short-circuit the plug while the charger is connected to an outlet. • Do not short-circuit the connector of the charger using a screwdriver, etc.
Page 8: Before Use
MM-601B • Do not use the accessory charger for any unit other than the MM-601B. • Remove the charger from the outlet when it is not in use. (3) Before Use Install the attached ferrite core near the connector of the weld-force sensor (optional).
Page 9: Features
MM-601B 2. Features Model MM-601B is a device for measuring the pressure of the electrodes of resistance welding machines that use a load cell (Load converter). With the optional special sensor, this device can easily measure welding force over a wide range (0.2 kg –...

Page 13 MM-601B (11) Connector for analog output This terminal is provided primarily to connect a measuring instrument such as an oscilloscope in order to monitor the applied force. When a force is applied to the force sensor, a voltage output is provided by the supplied analog output cable.
Page 14: Measurement Method
MM-601B 5. Measurement Method Caution • Prior to using the tester for the first time, be sure to charge the batteries, which may not be sufficiently charged immediately after purchase. Refer to “Chapter 6, (1) Charging” for the battery-changing procedure.
Page 15 MM-601B Welding Perform welding as slowly as possible so that no significant impact is applied to the weld-force sensor. Caution If “OVER!!” is indicated and the buzzer sounds intermittently at this time, stop welding immediately, as this indicates excessive weld force.
Page 16: Built-In Batteries
If this message appears, follow the steps described below to charge the batteries. In addition, keep in mind that you must fully charge the batteries prior to using the MM-601B for the first time. Note that this gauge can be used during charging.
Page 17: Replacement
MM-601B (2) Replacement The built-in batteries will last three to five years under normal usage conditions, and can be charged approximately 500 times for repeated use. (The service life varies depending on the frequency of use. The battery life will be shortened if stored for extended periods without being used.)

Page 20: Calibration
To maintain the performance of the MM-601B, it is necessary to calibrate it periodically. The calibration is carried out at our factory. Send us your weld-force sensor with the MM-601B for calibration. Because the conditions of degradation of the MM-601B differ depending on the operation environment, it is necessary to calibrate the MM-601B and the weld-force sensor together.
