SOURCE: Instantly output two preset settings by moving the
EZ-CHECK™ switch to the
“LO” position or “HI” position. For fast
three point checks select the “SET” position. The PIECAL 820
will remember the last “SET” value, even with the power off.
These values can easily be changed to suit the calibration requirements.
The values stored in the HI and LO positions are also used for Auto
Stepping.
READ: Slide the switch to the SET position. The PIECAL 820 will
display the current reading from the sensor or device being measured.
Slide the switch to MAX and the highest value measured since turn-on
or reset will be displayed; slide the switch to MIN and the lowest value
measured since turn-on or reset will be displayed.
