Product Description
• Easy to use
With the CL514-PLUS you can check & calibrate all
your RTD instruments and measure RTD Sensors.
Automatic indication of connections on the display
for simple hookups.
• Take it into the shop, plant or field
Carry it without worry - it comes protected with a
rubber boot and rugged, low profile switch. Easy to
operate even in the dark areas of the plant with the
backlit display.
• Calibrate directly in temperature (°C & °F)
Stop carrying around a decade box and RTD
resistance tables. The CL514-PLUS works with the
RTDs you use including Platinum 100 (alpha =
3850, 3902, 3926) & 1000 (alpha = 3850, 3750)
Ohm, Copper 10 & 50 Ohm, and Nickel 120 Ohm.
Easily set any value quickly to within 0.1° with the
adjustable digital potentiometer “DIAL” plus store
any three temperatures for instant recall with the HI/
SET/LO™ switch.
• Calibrate quickly with automatic output stepping
Choose between 2, 3, 5, 11 and 21 steps to
automatically increment the output in 100%, 50%,
25%, 10% or 5% of span. Select the step time to
match your system from 5, 6, 7, 8, 9, 10, 15, 20, 25,
30 and 60 seconds.
• Compatible with all 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
Troubleshoot sensor connections and find broken wires with patented technology. Connect your
two, three or four wire RTDs and the CL514-PLUS automatically detects the connections and
measures the RTD in degrees C or F.

CHANGING BATTERIES
Low battery is indicated by a battery symbol on
the display. Approximately one to four hours of
typical operation remain before the CL514-PLUS
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 (RTD Type, HI/SET/
LO Memories, etc., are reset to factory settings
when the batteries are removed.

Storing HI/SET/LO Outputs
STORING HI and LO Outputs
Choose this function to select commonly used temperature output values, and set high and low
values for stepping.
1) Store your high (SPAN) output temperature by moving the HI/SET/LO switch to the HI position
and turn the
e knob until the desired temperature is on the display. Press and hold the knob
until STORED appears to store the value. Release the knob.
2) Store your low (ZERO) output temperature by moving the HI/SET/LO switch to the LO position
and turn the
e knob until the desired temperature is on the display. Press and hold the knob
until STORED appears to store the value. Release the knob.
3) Instantly output your SPAN and ZERO temperature outputs by moving the HI/SET/LO switch
between HI and LO. You may also select any third temperature output (such as mid-range) using
the SET position on the HI/SET/LO switch.

Troubleshooting RTD Sensors
Troubleshooting RTD Sensors
When troubleshooting a problem with an RTD input it is useful to check that the sensor and the
wiring to the instrument is operating properly.
The PIE CL514-PLUS automatically detects 2, 3 and 4 wire RTD connections with a patented circuit.
It will also display the connections on the display and indicate when there is a missing connection
due to a loose connector, corrosion or a broken wire.
Here is an example of the CL514-PLUS reading a
sensor with all 4 wire connected.
Here is an example where connections are made to a
4 wire sensor and the CL514-PLUS indicates that only
Wires 1, 2 & 4 are connected. There may be a loose
connection or a break in wire 3 somewhere between
the sensor and the CL514-PLUS.
This is much simpler and quicker than going through
the process of testing each pair of wires to figure out
which, if any, connection is loose or which wire is
broken.
