With the CL541-PLUS you can
check and calibrate all your
thermocouple instruments and
measure thermocouple 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 millivolt source and
thermocouple tables, you can
calibrate directly in temperature
(°C and °F).
The CL541-PLUS
works with the T/Cs you use
including types J, K, T and E. 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 the
thermocouple inputs of smart
transmitters, PLCs, controllers
and multichannel recorders and
verify their outputs or displays.
Measure and trouble shoot
thermocouple sensor connections
and find broken wires or high
resistance junctions. Connect
your sensor and the CL541-PLUS
automatically measures the
thermocouple in degrees C or F.
