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 high-
voltage 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.

B. Setpoints
1. Storing Setpoints
The setpoint mode allows up to 9
setpoints to be set in non-volitile memory
for each range. The procedure is as
follows:
a. Set the output to the desired value.
b. Press shift followed by the “SET” key
c. Choose the desired setpoint storage
location by pressing a key (1-9).
d. Enter a new value and repeat steps 1
through 3 as needed, up to 9
setpoints for each range can be
stored.
2. Recalling Setpoints
a. To recall a setpoint press shift followed
by the”SPT” key.
b. You will be prompted to enter the
number of the desired setpoint
location set previously.
c. Press the desired location number and
the unit will go to that output.
3. Automated Stepping
The PTC8001 can auto-step through
some or all of the stored setpoints for a
given range. The procedure is as follows:
a. Press “Shift” followed by “Auto”.
b. “Auto SPT ?” will appear. Enter the
ending setpoint location. Example: if
you have all 9 setpoints stored but
only want to step through the first 3
then enter ”3” for this question.

c. The next screen prompts you to enter
the dwell time from 5 to 500 seconds.
Simply enter a number in that range.
d. Auto-step will begin.
e. To exit auto-step press the “CE” key or
enter a value.
4. Manual Stepping
The PTC8001 can be manually stepped
through all or some of the stored
setpoints. The procedure is as follows:
a. Press “Shift” followed by “Man”
b. Using the arrow keys, toggle up and
down through the stored setpoints.
c. To exit press “CE” or simply enter a
new output value.
3. Connection Diagrams
& Instructions
A. Sourcing Resistance
1. Select the RTD mode.
2. Connect device under test as shown.
3. In the RTD mode, use the RTD key to choose
the desired range.
4. The PTC8001 is able to handle up to a 3 mA
excitation on the Resistance Simulation
Range. Exceeding these limits will result in a
warning on the display. See Section E. for
RTD Transmitter calibration.
