52.000 mA (-25.00 to 125.00%) signals with greater
accuracy than a typical multimeter.
• Power & measure 2 wire transmitters
The 850 can simultaneously output 24V DC @ 20 mA
or 40V DC @ 50 mA 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 (4-20 mA only) with built-in 250
ohm resistor simplifying hookups with HART
communicators.
The 850 has an internal 40 V power supply which is able
to drive transmitters and positioners in 10-50 mA loops.
Some other brands of calibrators have a 24 V supply
which are unable to supply the power required to
properly drive these control devices.
• Read DC volts
The 850 can measure from 0.000 to 10.250 V, -999.99
to 999.99 mV, -99.999 to 99.999 mV and 0.00 to 60.0
VDC. Use it to check loop power supplies, I/V converters,
1 to 5 Volt signals, and other voltages.

Typical problem found with Leak Detection
Have you ever replaced a “faulty” transmitter only to find the problem was somewhere else in the loop? And did you end up
throwing the transmitter away after you fixed the other problem “just in case” the transmitter was faulty?
If you find a loop where the transmitter is calibrated correctly but all the readings elsewhere in the loop have a fixed offset this is
due to a Zero Shift. This zero shift is typically caused by some current in the loop bypassing the transmitter. This might be caused
by ground faults, moisture or corrosion.
If you have some loops that are erratic after it rains there may be moisture present in a junction box or where insulation has
broken down. Turn on Ground Leak Detection and use the PIE 850 to power up the loop. Any current that isn’t controlled by the
transmitter or other current control element will be indicated as leakage on the PIE 850 display. Undetected current leaks may cause
calibration errors which can lead to dangerous operating conditions or catastrophic results.
The PIE 850 powers up the 2-Wire transmitter or loop and indicates the total current and the uncontrolled current. This provides
information useful in troubleshooting loop errors.
Troubleshoot Loop Problems
Automatic indication of Loop Current
and Leakage Current (US Patent
#7,248,058) in both 4-20 and 10-50
mA loops. Measure ground current
leakage from faulty wiring, flooded
conduit and corrosion bridges to
help you decide if there is a wiring
problem in the loop (diagrams below).

Box
Here is a loop where a technician has just recalibrated
the transmitter but the control room still sees a problem.
The problem started just after a rainstorm.
Using the PIE 850 to power up the loop the technician detects
a leakage of 0.45 mA - approximately the offset seen in the
control room. He walks the loop and opens a junction box
releasing a stream of water. The loop is again in control.
850 detects uncontrolled
current in the loop due
to a flooded junction
box.

• Designed for you by experienced calibrator manufacturers
PIE 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 850 improves upon other brands by including a rubber boot, backlit
display with larger digits, troubleshooting tools, higher accuracy and more ranges for flexibility.
Evolutionary Design
* PIE Calibrators are not manufactured or distributed by Fluke Corp or Altek Industries Inc, manufacturers of Altek Calibrators.
Become a Loop Detective - Locate hidden loop problems with LoopScope
When you need to find out why a loop is out of control and all the wiring seems to be in order turn on the 850’s LoopScope and
simultaneously see all the parameters of the loop. The LoopScope simultaneously displays the current, DC voltage and total
resistance in the loop. Observing the SUPPLY (DC voltage) and the LOAD (resistance) lets you see if the loop power supply has
enough capacity to power all the devices in the loop.
By observing all three signals at the same time you can see how the voltage and resistance respond as the current changes. If
the voltage drops too far as the current goes up you may need a power supply with more capacity or the power supply itself may
be failing. If the resistance in the loop is too high you may have more devices in the loop than the power supply can handle or there
may be an instrument in the loop that is drawing too much power and requires replacement.
Why buy a PIE calibrator with loop diagnostics
Undiagnosed loop problems often cause calibration errors which can
lead to dangerous operating conditions or catastrophic results. Only PIE
makes troubleshooting multifunction calibrators that can detect and
indicate these problems due to the patented troubleshooting features.
With LoopScope running the
850 simultaneously controls
and displays the loop current
while measuring & displaying
the power supply voltage and
loop load in ohms.
