Multifunction Process Calibrator
Carry six single function
calibrators in the palm of your
hand with the PIECAL 820
• Lighten up your toolbox
Pocket sized calibrator replaces toolbox of single function devices
Milliamp • Voltage • Frequency
Thermocouples • RTDs • Check Continuity
• Technician friendly operation
Intuitive EZ-DIAL Double Click Menu makes it easier to setup than
other multifunction calibrators. Uses the same menus as the single
function PIE Evolution Calibrators. Icons on the display indicate
where to plug in the test leads.
• Use it as a milliamp and voltage calibrator
Source 0 to 24.00 mA, 0 to 10.25 V and -10.00 to 80.00 mV dc
Read to 24.00 mA, 10.25 V, 60.0 V and -10.00 to 80.00 mV dc
Simulate 2-Wire Transmitters
Power up transmitters & loops with the built-in 24 V power supply.
Simplify HART hookups with built-in 250 Ohm resistor
PIECAL 820
• Calibrate directly in temperature (°C & °F)
The PIECAL 820 works with the instruments you use.
Types J, K, T, E, R, S, B, N, G, C, D, L (J DIN), U (T DIN) and P
(Platinel II)
Pt 100 Ohm (3850, 3902, 3916, 3926) & 1000 Ohm (3850)
Copper 10 & 50 Ohm, Nickel 110 and 120 Ohm
• Checkout flow and vibration systems
Source & read frequency to 2000 CPM (Counts-Per-Minute), 999.99
Hz, 9999.9 Hz & to 20.000 kHz.
• Troubleshoot loop & wiring problems
‘Beep’ out connections with the built-in continuity checker.
• Easy to read
Turn on the backlight & easily see the display in dark areas of the plant.
• Quickly set any three outputs plus automatic stepping & ramping
Easily set any value quickly with the adjustable “DIAL” plus store any three output settings for instant recall with
the EZ-CHECK™ switch. Choose between 2, 3, 5 & 11 steps to automatically increment the output in 100%, 50%,
25% or 10% of span. Select RAMP to smoothly increase and decrease the output between Zero and Span. Set
step/ramp time to match your system from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 and 60 seconds.
• Measure temperature sensors, frequency pickups, loop currents and voltage levels
Check the values of your process sensors. Instantly recall MAX and MIN values to see process variability.
• Evolutionary design
PIECAL Calibrators are designed and built by members of the same team that designed and built the calibrators
manufactured by Fluke* under the Altek* label. The PIECAL 820 improves upon other brands by including a rubber
boot, a backlit display with larger digits, higher accuracy and more ranges for greater flexibility.
Actual Size
* PIECAL Calibrators are not manufactured or distributed by Fluke Corp or Altek Industries Inc, manufacturers of Altek Calibrators.
Milliamp Calibrator
• Easy to use
With the PIECAL 820 you can check,
calibrate and measure all your
current signal instruments in a 4 to
20 milliamp DC loop. It can be used
at any access point in your loop.
Source & Read 0.00 to 24.00 mA, Simulate a 2 Wire
Transmitter or use the PIECAL 820 to simultaneously
power your 2 Wire Transmitter and measure its output.
• Source milliamps
Calibrate recorders, digital indicators, stroke valves or
any instruments that get their input from a 4 to 20 mA
loop. Easily set any value quickly to within 0.01 mA with
the adjustable digital potentiometer “EZ-DIAL” or use
preset 4.00 mA (0.0%) and 20.00 mA (100.0%)
EZ-CHECK™ settings.
Voltage Calibrator
• Source mV & V dc
With the PIECAL 820 you can check,
calibrate and measure all your
voltage, millivolt and pH signal
instruments in your plant. Source 0
to 10.25 V dc and -10.00 to 80.00
m V.
• Calibrate using loop power
Check loop wiring and receivers by using the PIECAL
820 in place of a 2 Wire transmitter. Uses any loop
power from 2 to 60 V DC.
• Read loop current
Check controller outputs or measure the milliamp signal
anywhere in the loop. The PIECAL 820 measures 0.00
to 24.00 mA (-25.0 to 125.0%) signals with greater
accuracy than a typical multimeter.
• Power & measure 2 wire transmitters
The PIECAL 820 can simultaneously output 24V DC to
power any and all devices in a process loop using the
internal batteries and internal switching power supply,
while measuring the output of a 2 Wire Transmitter and
any other loop devices. Powers HART™ transmitters
with built-in 250 ohm resistor simplifying hookups with
HART communicators.
• Read DC volts
The PIECAL 820 can measure from 0 to 10.25 V, -10.00
to 80.00 mV and 0.0 to 60.0 VDC. Use it to check loop
power supplies, I/V converters, 1 to 5 Volt signals, and
other voltages.
Frequency Calibrator
• Calibrate flow meters and frequency instruments
Generate zero crossing square
waves to check, calibrate and
measure all the frequency signal
instruments in your plant. Source
and read frequencies from 1 to 2000
CPM (Counts-Per-Minute), 0.01 to
999.00 Hz, 0.1 to 9999.9 Hz and
0.001 to 20.000 kHz.
Thermocouple Calibrator
• Calibrate directly in temperature (°C & °F)
Stop carrying around a millivolt
source and thermocouple tables.
The PIECAL 820 works with the
thermocouples you use including
types J, K, T, E, R, S, B, N, G, C, D,
L (J-DIN), U (T-DIN) and P (Platinel
II). Easily set any value quickly to
within 0.1° with the adjustable digital
potentiometer “EZ-DIAL” plus recall
any three temperatures for instant
recall with the EZ-CHECK™ switch.
• Checkout optical pickups
The PIECAL 820 has a green LED that flashes in sync
with the output frequency. Select a frequency and hold
the calibrator up to the optical sensor.
• Measure thermocouple sensors
Trouble shoot sensor connections and find broken wires
or corroded connections. Connect your thermocouple
with a miniature thermocouple connector and the
PIECAL 820 measures the probe in degrees C or F.
RTD, Resistance Calibrator
• Easy to use
With the PIECAL 820 you can check
& calibrate all your RTD instruments
and measure RTD Sensors.
Automatic indication of connections
on the display for simple hookups.
• Calibrate directly in temperature (°C & °F)
Stop carrying around a decade box and RTD resistance
tables. The PIECAL 820 works with the RTDs you use
including Platinum 100 (alpha = 3850, 3902, 3916,
3926) & 1000 (alpha = 3850) Ohm, Copper 10 & 50
Ohm, Nickel 100 and 120 Ohm. Easily set any value
quickly to within 0.1° with the adjustable digital
potentiometer “EZ-DIAL” plus store any three
temperatures for instant recall with the EZ-CHECK™
switch. Or use like a decade box from 0.0 to 401.0 and
from 0 to 4010 Ohms.
Continuity Checker
• Troubleshoot wiring and connection problems
Use the built-in continuity checker to look at wiring and
connections during installation or to locate shorts.
Beeps from 0 to 100 Ohms.
• Compatible with ALL process instruments
No competitor’s calibrator is compatible with as many
process instruments! Connect directly to the RTD inputs
of smart transmitters, PLCs, DCS and multichannel
recorders and verify their outputs or displays. Works with
older instruments with fixed excitation currents and
newer multichannel instruments that switch the excitation
current between input channels.
• Measure RTD sensors
Trouble shoot sensor connections and find broken wires
with patented technology. Connect your two, three or
four wire RTDs and the PIECAL 820 measures the RTD
in degrees C or F.
