The following definitions apply to the terms
“Warning” and “Caution”.

• “Warning” identifies conditions and actions
that may pose hazards to the user.

• “Caution” identifies conditions and actions
that may damage the instrument being used.

Use the calibrator only as specified in this
manual, otherwise injury and damage to the
calibrator may occur.

Warning

To avoid possible electric shock or

personal injury:

• Do not apply more than the rated voltage.
See specifications for supported ranges.

• Follow all equipment safety procedures.

• Do not use the calibrator if it is damaged.
Before you use the calibrator, inspect the
case. Look for cracks or missing plastic. Pay
particular attention to the insulation
surrounding the connectors.

• Select the proper function and range for your
measurement.

• Make sure the battery cover is closed and
latched before you operate the calibrator.

• Remove test leads from the calibrator before
you open the battery door.

• Inspect the test leads for damaged insulation
or exposed metal. Check test leads continuity.
Replace damaged test leads before you use
the calibrator.

• Do not use the calibrator if it operates
abnormally. Protection may be impaired.
When in doubt, have the calibrator serviced.

• Do not operate the calibrator around
explosive gas, vapor, or dust.

• Disconnect test leads before changing to
another measure or source function.

• When servicing the calibrator, use only
specified replacement parts.

• To avoid false readings, which could lead to
possible electric shock or personal injury,
replace the battery as soon as the battery
indicator appears.

Caution

To avoid possible damage to calibrator or

to equipment under test:

• Disconnect the power and discharge all high­voltage capacitors before testing resistance
or continuity.

• Use the proper jacks, function, and range for
your measurement or sourcing application.

2. Quick Start Instructions

A. Key Functions

Key Function

Input/Output Toggles the function selected

from measurement mode to
source mode.

TC Pressing the “TC” or

“Thermocouple” key toggles
through all available TC types
as well as direct mV output.

RTD Pressing the RTD key toggles

through all available RTD types
as well as direct ohms output.

°F/°C Toggles between °F and °C
0-9 keys These keys allow a user to

enter an output value.
Example: to output 20 mV
select mV output and Press
the “2” key then the “0” key
followed by the “ENTER” key.

Arrow ↑↓ These keys allow small

changes to be made to an
output value. Press either the
up or the down key to set the
value as desired.

CE The clear entry key allows the

user to clear a value before the
enter key is pressed.

Shift This key has a blue text color

and acts as a second function
key to all keys that have an
associated second function.
