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.

• When using the probes, keep your fingers away from the probe contacts.

Keep your fingers behind the finger guards on the probes.

• 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.

• 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 personal injury or damage to the calibrator, use only the specified replacement parts and do not allow water into the case.

2.1 Inputs and Primary User Interface

The Calibrator has two numeric displays. The main display area displays the signal which is being sourced or measured. The smaller numeric display area is used in the mA modes to display the percent of range.

Normally values in the 4mA to 20mA range correspond to a percentage from 0% to 100%. The unit can also be configured for 0 to 20 mA fullscale.

The CSC101 has one input terminal located on the top of the unit. These terminals are provided for all milliamp functions and voltage functions. The terminals will accommodate standard banana plugs.

The CSC101 has an knob and a series of key used to operate and configure the unit.

Figure 1 shows the layout of the calibrator keypad while Table 1 lists the calibrator's components and describes their functions.

3. Operation in the Current Mode (4mA to 20mA)

The CSC101 offers four (4) different operational functions when operated in the current or milliamp mode. These functions are:

1. mA Source - Current can be sourced from the CSC101 over a 0 to

24mA range into loads of up to 1000 ohms.

2. mA Simulate - The CSC101 can act like a 2-wire transmitter by controlling the loop current when power comes from an external power supply.

3. mA Measure - The CSC101 displays input current over a range of 0 to

24mA.

4. mA Measure with Loop Power - Displayed as mA Measure 24V, this mode measures current while simultaneously supplying 24 volts to the loop.

5. Advanced Features

The CSC101 has many advanced features that are available through the

Calibrator Setup Menus. How the features are enabled and what they do is described below.

5.1 Step and Ramp Operation

The CSC101 has several unique features that are helpful aids when doing milliamp calibrations. The percent keys allow the user to the output to

0% of scale, 100% of scale or in 25% steps from 0 or 4 to 20 mA. The "Step/

Ramp" allows hands free operation by automatically stepping or ramping the milliamp output.

5.1.1 Manual Stepping

1. Use the main menu to set the CSC101 to source or simulate current.

2. Press the "25%" key to step the output in 25% increments from 4mA to

20mA and 20mA to 4mA.

5.1.2 Automatic Stepping & Ramping

1. Set the CSC101 to source or simulate current. See figures 2 & 3.

2. The CSC101 has separate Auto ramp and step times. Use the menu system to set the step or ramp time. (see section 2.2 Calibrator

Configuration)

3. Once the desired times are set use the {ramp/step} to continually ramp or step the value from 0% to 100% and back.

5.2 Valve Test

The has CSC101 has a Valve Test mode for verifying proper operation of valves. In Valve Test user can step the output to the following values: 3.8 mA, 4.0mA, 4.2mA, 8.0 mA, 12.0 mA, 16.0 mA, 19.8 mA, 20.0 mA, 20.2 mA.

1. Use the main menu to set the CSC101 to source or simulate current.

2. If Valve Test is not enabled use the menu system to enable it. (see section

2.2 Calibrator Configuration)

3. The Press the Automatic Stepping Function or the "25%" key to step the output to verify the proper valve operation.

5.3 Flow Calculation

The has CSC101 has a Flow Calculation mode for displaying flow (0-100%) as a function of mA. Flow is displayed in the percent display. Flow

Calculation can be enabled through the menu system. (see section 2.2

Calibrator Configuration)

5.4 Hart 250

Ω Resistor

The has CSC101 has the ability to insert a 250

Ω resistor in series with the power supply in order to facilitate the use or a Hart communicator. The Hart resistor can be enabled through the menu system. (see section 2.2

Calibrator Configuration)
