EZ-CHECK™ SWITCH
q
SOURCE: Instantly output two preset RTD
temperatures by moving the EZ-CHECK™ switch to
the "LO" position or "HI" position. For fast three
point checks select the "DIAL" position. The
PIECAL 211 will remember the last "DIAL"
value, even with the power off.
These values can easily be changed to suit the
calibration requirements. The temperatures stored in
the HI and LO positions are also used for Auto
Stepping.
READ: Slide the switch to the DIAL position. The
PIECAL 211 will display the current temperature from
the RTD sensor. Slide the switch to HI and the
highest temperature measured since turn-on or reset
will be displayed; slide the switch to LO and the
lowest temperature measured since turn-on or reset
will be displayed.
