CL120 Series Calibration
COOL/HEAT Source

The CL120 Series is capable of
simultaneous heat and cool
sourcing in 1 unit and is available
with either 1 or 2 modules.
You select the combination of
modules: COOL source only,
HEAT source only, COOL source
and HEAT source, or 2 HEAT
sources. Both the COOL and
HEAT sources are available
with the universal jaw or a
“five hole block.”

A dual module system with
simultaneous cooling and heating
is a significant advantage, because
temperature sensors are rarely
tested at only 1 temperature.
The most common procedure is
to test at 0°C (32°F) and at the
maximum temperature, thereby
characterizing the offset and gain
errors. Two HEAT source systems
may also be ordered.

CL134 Series Temperature
Source/Measure

The CL134 Series has the same
features as the CL120 but includes
measurement capabilities. This
additional feature simplifies the
testing of temperature sensors by
conveniently housing both the
source and measure in one
package. The CL134 Series has
3 distinct capabilities:

1. A COOL source (either universal
jaw or “5 hole block”) with
range down to -30°C (-22°F)

2. A HEAT source with range to
500°C (932°F) with universal
jaw or range to 700°C (1292°F)
with a “5 hole block;” the CL134
Series may be ordered with
2 HEAT sources and no
COOL source

3. Measures thermocouples, RTDs,
current and voltage
