F490A is a portable handheld indicator for load cells. 

The outstanding advantages of the Portable Digital Force Indicator F490A:  

• Capable of continuous use for approx. 30 hours 
  
• Multi-calibration function that allows six units of load cells to be recorded data 
  
• Stores 20,000 data on the internal memory storage 
  
• High accuracy & High stability: Non-linearity: 0.02%F.S. / Zero drift: 0.3μV/°C / Gain drift: 5ppm/°C  
  
• Lightweight design of 290g for portable use  
  
• Measurement data is recorded in CSV format in its internal memory  
  
• Recorded data can be referred to and copied via a USB interface  
  
• Various display modes such as graphic display and recorded data display prepared  
  
• 4 types of Hold functions can set the data observation range  

Detect failure on a regular basis by measuring the reliability of the facility that is combined with a load cell. Recording ability ease the facilities management. 

New functions are added to F490A!

• Captures momentary press force by high-speed sampling of 1200 times/sec 
  
• Minus calibration supporting both compression and tension force 
  
• Stores last calibration date & calibration info 
• In addition, a terminal block connector that allows connecting load cells to not only a connector but also a cable with free end is available as an option (sold separately). 

F490A achieves high accuracy & stability! 

Application example - Maintenance inspections of press machine 

The output value from the load cell embedded in a press machine may change due to fatigue. Therefore, replacement timing needs to be considered by running periodic checks.   

F490A can store 20,000 pieces of data in its internal memory storage. It's perfect for checking the output change of a press machine on a daily basis! 

Plus, data can be transferred to PC. 

F490A achieves high accuracy & stability even though it's a portable type indicator. As well as a periodic check of press machines, by the new functions added this time, measurement of momentary force and malfunction check of load cells too can be performed.
