q EZ-CHECK™ SWITCH
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 820PM 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 820PM will display the current input
value. Slide the switch to HI and the
highest value measured since turn-on or
reset will be displayed; slide the switch to
LO and the lowest value measured since
turn-on or reset will be displayed.
Test leads with shielded or non
shielded banana plugs may be plugged
into the protected banana jacks labeled
1 through 6.

e EZ-DIAL™ KNOB
SOURCE: Turn the knob to adjust the
output level. Turn clockwise to increase
the output, counter clockwise to
decrease the output in one least
significant digit step at a time. Push
down and turn the EZ-DIAL knob for
faster dialing.
Press and hold the knob for two seconds
to store desired EZ-Check™ HI/LO
points in SOURCE mode. Continue to
press and hold the knob for two more
seconds to start the automatic ramping.
READ: Press and hold to transfer
the current temperature into the
EZ-Check™ MIN/MAX points. This
clears the MIN/MAX readings which
will update as the input value
changes.
Double Click the EZ-DIAL knob to
change the function of the calibrator
and to select ranges, units and other
user settings.
