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 without 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 Platinm 100 (alpha = 3850,
3902, 3926) & 1000 (alpha = 3850, 3750) Ohm,
Copper 10 & 50 Ohm, Nickel 100 and 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
OMEGA 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, 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

Trouble shoot sensor connections and find broken wires with patented technology. Connect
two, three or four wire RTDs and the CL514-PLUS automatically detects the connections and
measures the RTD in degrees C or F.
