Operating Instructions
FIELD & BENCH USE
PIE 820-ELITE comes with a carrying case designed for hands-
free operation and a rubber boot with a built-in tilt stand. The PIE
820-ELITE is held in the case by elastic straps for use with the
carrying case open. The tilt stand is easily raised by pulling the
stand until it locks into place.
CHANGING BATTERIES
Low battery is indicated by “BAT” on the display. Approximately
one to four hours of typical operation remain before the PIE
820-ELITE will automatically turn off. To change the batteries;
remove the rubber boot, remove the battery door from the back of
the unit by sliding the door downward. This allows access to the
battery compartment. Replace with four (4) “AA” 1.5V batteries
being careful to check the polarity. Replace the battery door and
replace the boot. All stored configuration options (T/C Type,
EZ-CHECK Memories, etc.) are reset to factory settings when the
batteries are removed.
Note: Alkaline batteries are supplied and recommended for
typical battery life and performance. Optional rechargeable
batteries (charged externally) are available.

Operating Instructions
STORING HI and LO EZ-CHECK Source Outputs
Speed up your calibration by storing Span & Zero output setting
for instant recall with the EZ-CHECK switch.
1) Store your high (SPAN) output temperature by moving the
EZ-CHECK switch to the HI position and turning the EZ-Dial
knob until the desired output value is on the display. Press
and hold the EZ-Dial knob until STORED appears to store
the value. Release the EZ-Dial knob.
2) Store your low (ZERO) output value by moving the EZ-CHECK
switch to the LO position and turning the EZ-Dial knob until
the desired output value is on the display. Press and hold the
EZ-Dial knob until STORED appears to store the value.
Release the EZ-Dial knob.
3) Instantly output your SPAN and ZERO output settings by
moving the EZ-CHECK switch between HI and LO. You may
also select any third output setting (such as mid-range) using
the SET position on the EZ-CHECK switch.
Connections
PIE 820-ELITE has banana jacks compatible with unshielded or
retractable banana plugs. Included with your calibrator are: a
pair of test leads with alligator clips for mA, V, pH & Hz
connections. Four test leads with spade lugs are also included
for 2, 3 and 4 Wire RTD connections. Thermocouple connections
are made through a miniature thermocouple socket.

qEZ-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 PIE 820-ELITE
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 PIE 820-ELITE 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.

Select “SOURCE” to output mA, V, T/C, Ohms, RTD or frequency.
Select “READ” to read mA, V, T/C, Ohms, RTD or frequency.
eEZ-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 steps 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.
SELECTING FUNCTIONS
The EZ-DIAL knob is used to setup the PIE 820-ELITE to match
the instrument to be calibrated or signal to be measured. Each
time you turn on the PIE 820-ELITE the LCD displays the fol-
lowing screen for about 1 second followed by operating in the
function used the last time it was operated.
Double Click the EZ-DIAL knob to change the function of the
calibrator and to select ranges, units and other user settings.
Each function (mA, V, T/C, Ohms, RTD, Frequency) has two
pages of menus. The first menu page has settings for the func-
tion and the second menu page has settings for STEPPING,
AUTO OFF and BACKLIGHT. Settings are remembered even
with the power off but are reset when the batteries are changed.

To change the Automatic Stepping settings
Double click the eDIAL KNOB at any time the unit is on and
the following typical display (will be different for each FUNCTION)
will appear for 15 seconds:
Turn the eDIAL KNOB to move to the second menu page.
Turn the eDIAL KNOB to move through the menu. Press the e
DIAL KNOB to toggle between OFF and ON or to change the

To start the Automatic Stepping
Start automatic stepping or ramping by placing the EZ-CHECK
Switch into the HI or LO position then press and hold the e
DIAL KNOB for 6 seconds (the word STORE will appear on the
display after 3 seconds and continue to press the EZ-DIAL
KNOB) until the word STEPPING appears on the display. The
word STEPPING will appear on the display anytime the selected
automatic function is running. Stop the stepping by again
pressing and holding the eDIAL KNOB for 3 seconds.
BACKLIGHT - If BACKLIGHT is ON the backlight will light all the
time the unit is powered up. For maximum battery life turn the
backlight off when using the calibrator in areas with enough
ambient light to read the display.
STEPS - pressing the knob will cycle through 2, 3, 5, 11 and
RAMP. The endpoints of the steps or ramp are based on the
values stored in the HI and LO EZ-CHECK outputs.
2 steps will automatically switch between the values stored in
the HI & LO EZ-CHECK (0 & 100%).
3 steps between the HI, Midpoint and LO EZ-CHECK (0, 50
& 100%).
5 steps between the HI and LO EZ-CHECK in 25%
increments (0, 25, 50, 75 & 100%).
11 steps between the HI and LO EZ-CHECK in 10%
increments (0, 10, 20...80, 90 &100%).
RAMP continuously ramps up and down between the HI and
LO EZ-CHECK outputs.
STEP TIME - pressing the knob will cycle through 5, 6, 7, 8, 9,
10, 15, 20, 25, 30 and 60 seconds.

there is an uncontrolled loop, a transmitter with upscale burnout
and bad or missing sensor or a short the display shows "OVER

Note: Many installed transmitters will normally indicate 0.01 to
0.02 mA leakage without significant control problem. Unstable
readings may indicate loose connections or the presence of
moisture.
