With the CL514-PLUS you can
check and calibrate all your RTD
instruments and measure RTD
sensors. Automatic indication of
connections on the display for simple
hookups. Take it without worry into
the shop, plant or field. 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.
Stop carrying around a decade box
and RTD resistance tables, you can
calibrate directly in temperature
(°C and °F). The CL514-PLUS works
with a wide variety of RTD curves
including Platinm 100 (alpha = 3850,
3902, 3926) and 1000 (alpha =
3850, 3750) Ω, Copper 10 and 50 Ω,
Nickel 100 and 120 Ω. Easily set any
value quickly to within 0.1° with the
adjustable digital potentiometer
"DIAL" plus store any three
temperatures for instant recall.
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.
Connect directly to RTD inputs of
smart transmitters, PLCs,
controllers and multichannel
recorders and verify their
outputs or displays.
Measure and trouble
shoot RTD sensor
connections and find
broken wires. Connect
your 2, 3 or 4 wire RTD
sensor and the
CL541-PLUS
automatically measures
the RTD in °C or °F.
