1. Introduction
The AMETEK CSC201 Compact Signal Calibrator is a handheld, battery-
operated instrument that measures and simulates physical and electrical
parameters. The calibrator has the following features and functions:
• A large easy to read display used to display all supported physical and
electrical parameters.
• Temperature measurement and simulation using resistance temperature
detectors (RTDs), thermocouples (TCs) and thermistors.
• Signal measurement and sourcing capabilities for resistance and voltage
(millivolts) in the RTD and TC mode.
• Extended and comprehensive pressure measurement capabilities with
JOFRA APM
• A thermocouple (TC) input/output terminal with automatic reference-junction
temperature compensation.
• An interactive menu
• Complete RS232 interface for remote control

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
The CSC201 is designed to calibrate and measure low voltage process
signals. To ensure the safety of the operator, DO NOT connect the CSC201
to inputs greater than 30 Volts.
!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.
• Never touch the probe to a voltage source when the test leads are
plugged into the current terminals.
• 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.
• When using the probes, keep your fingers away from the probe contacts.
Keep your fingers behind the finger guards on the probes.
• Connect the common test lead before you connect the live test lead.
When you disconnect test leads, disconnect the live test lead first.
• 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.

• When using a pressure module, make sure the process pressure line is
shut off and depressurized before you connect it or disconnect it from the
pressure module.
• 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.
• To avoid a violent release of pressure in a pressurized system, shut off the
valve and slowly bleed off the pressure before you attach the pressure
module to the pressure line.
• To avoid personal injury or damage to the calibrator, use only the
specified replacement parts and do not allow water into the case.
!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.
• If the message changes to "OL" the range limit is exceeded and the
pressure source must immediately be removed from the APM to prevent
damage to the pressure transducer inside.
• Maximum torque allowed is 13.5 Nm/10 ftlbs. NEVER exceed the torque
allowed.
• To avoid damaging the plastic lens and case, do not use solvents or
abrasive cleansers.
Clean the calibrator with a soft cloth dampened with water or water and mild
soap.

2.1 Main Display
Figure 3. Display
The display of the calibrator, shown in Figure 3, is divided into two sections:
the main display and the menu bar.
The main display is used for both measuring and sourcing.
The menu bar is used to setup the display to perform the desired function.
Table 3 explains the different parts of the display:
Table 3: Display Functions
No. Name Description
1Primary Parameters Determines what parameter is going to be measured or
sourced.
The available options are TC (thermocouple), RTD, and
PRESSURE.
2Input/Output control Switches the display between input mode (read), and
output mode (source).
3Additional Settings Available only for TC (thermocouple), and RTD mea-
surements. For TC this setting turns the CJC (Cold
Junction Connection) on and off.
For RTD measure [RTD IN], his setting sets the number
of wires used in the measurement (2-wire, 3-wire, or
4-wire)
4 Units Shows what unit the measurement or source value is in.
Available options are °C, °F and K for RTD and TC.
5Sensor Types Allow for measurements to be made for different types
of RTDs and TCs. All types are shown in the
Specifications.
6Numeric Displays Display the numeric values of the signal being mea-
sured, or sourced. An “OL” reading indicates an out of
range or overload condition.

2.2 Menu Bar
The parameters on the display are controlled by the menu bar, which is
located at the bottom of the LCD. The function keys (F1, F2, and F3) are
used to navigate through all the levels and choices of the menu bar. Refer to
the menu tree for a clarification on the layout of all the levels.
The top level of the menu is the home menu. It can be accessed anytime by
pressing the HOME key. There are two variations of the home menu: the
input home menu and the output home menu.
There are up to three options for the input home menu. They are
[CONFIG], [ZERO] and [MORE]. [CONFIG] is used to enter the parameter
selection menu. [ZERO] is only available when the pressure mode is
selected. [MORE] allows access to further menus.
In the output home menu there are three active options, [CONFIG], [STEP]
or [RAMP] and [MORE]. [CONFIG] and [MORE] serve the same purpose as
in the input home menu. STEP or RAMP either steps or ramps the output.
The contrast menu is usually the next menu level. Its options are
[CONTRAST], [NEXT], and [DONE]. The [CONTRAST] option is used to
adjust contrast. [NEXT] proceeds to the auto off main menu, and [DONE]
returns to home menu. Contrast is adjusted using the cursor keys.
The auto off main menu contains the options [AUTO OFF], [NEXT], and
[DONE].
The [AUTO OFF] option is used to turn the automatic shutoff on and off and
set the amount of time the unit needs to stay dormant to shut off. [NEXT]
and [DONE] return to the home menu.
