EZ-Check™ Switch/EZ-Step™ Push-button

For Source - Slide the switch to select from three user 
stored values for the desired calibration points. The 
HI, DIAL and LO values can easily be changed to suit 
the calibration requirements. Press the push-button 
like a stopwatch to start or stop the totalizer output.
For Read - Slide the switch to the DIAL position. The 
Model 541 will begin making readings.  Slide the 
switch to high and you will get the highest point read 
and then slide the switch to the low position and you 
will get the lowest range. Press the push-button like a 
stopwatch to start or stop the totalizer counting 
pulses.
