Process Calibrator - mA • V • TC • Ohms • RTD • Hz

•  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 PIECAL Evolution Calibrators.
Icons on the display indicate where to plug in the test leads.

Use it as a milliamp and voltage calibrator
Source 0.00 to 24.00 mA, 0.00 to 10.25 V dc and 0.00 to 80.00 mV
Read to 24.00 mA, 00.00 to 10.25 V 0.0 to 60.0 V and and 0.00 to 80.00 mV
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

•  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 100 and 120 Ohm
•  Checkout flow and vibration systems
Source & read frequency to 2000 CPM (Counts-Per-Minute), 999.00
Hz, 9999.9 Hz, 9.9999 kHz & 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, 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
Advantages of the PIECAL 820 over the Altek 820
•  Automatic stepping & ramping
Setup 2, 3, 5 & 11 steps or continuous ramp from 5 to 60 seconds to match your test procedures
•  Larger Display with Backlight
Easy viewing in dark locations. Icons on display show where to plug in test leads.
•  More Resistant to Accidental Damage
Rubber Boot and Stronger Switches
•  More Thermocouple & RTD ranges with 0.1° resolution and better accuracy
Compatible with smart transmitters, multichannel recorders, PLCs and DCSs
•  Smaller & 25% lighter
Pocket sized and easier to carry
•  LED for optical pickups
LED flashes green in synch with frequency output. Illuminates red for overload conditions.
•  Includes Certificate of Calibration
All PIECAL Calibrators come with a free signed and dated certificate. Altek's come only with an unsigned Statement of Calibration Practices with a certificate of calibration available for an extra charge.
