Current Meter Counter Operation 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

The Current Meter screen data is presented as shown above.  
 
 
 
1. Press “Start” (right hand button) and the count, 
elapsed time and velocity will be zero’d. The / will start 
toggling between / and \. 
 
 
 
 
 
2. When the first meter pulse is detected, the elapsed 
timer will start. The count and velocity will also be 
updated as pulses are detected. 
 
 
 
 
 
3. When the elapsed timer exceeds the measurement 
interval, and a meter pulse is detected, the timer will be 
stopped. The final count, elapsed time and the 
calculated velocity are all displayed. 
 
 
4. If “Stop” (left hand button) is pressed during a measurement, the count, elapsed time and 
velocity are frozen at that point.
