Overview
This document provides detailed instructions for using the ASC-400 calibrator to measure and source various electrical parameters, including current (mA), temperature, pressure, voltage, frequency, and resistance. It includes guidelines for setting up and operating the device, as well as safety precautions.
Measuring Current (mA)
To measure mA, enter edit mode, select 'Current' from the Lower Mode list, choose the desired Test Mode, Range, Power Source, and Units, then accept the selections and connect the leads as shown in Figure 3.
Measuring Temperature
  • Using Thermocouples (TC): The ASC-400 supports various TC types and offers three cold junction modes: CJ Auto, CJ Off, and CJ Manual. Follow the setup instructions to measure temperature using thermocouples.
  • Using Resistance-Temperature-Detectors (RTDs): The calibrator supports two, three, and four-wire RTDs. Follow the setup instructions to measure temperature using RTDs.
Measuring Pressure
Connect the pressure module to the calibrator, select 'Pressure' from the mode list, choose the pressure type and unit, and zero the pressure module if necessary. The calibrator can measure pressure in two different units simultaneously.
Using Source Modes
The ASC-400 can generate signals for testing and calibrating instruments. It can source mA, voltage, frequency, pulses, and simulate RTD and thermocouple outputs. Follow the setup instructions for each parameter.
Safety and Precautions
  • When measuring pressure, ensure to shut off the valve and bleed off pressure before attaching the module.
  • Avoid overpressure and corrosion by adhering to the module's specifications.
Additional Notes
  • For best accuracy in temperature measurements, allow time for stabilization.
  • Use appropriate connectors to avoid errors.
  • Custom RTD settings can be configured using the Calendar-Van Dusen equation.
RTD Coefficients
The document provides coefficients for different RTD types (PT385, PT3926, PT3916) across various temperature ranges, essential for accurate temperature measurement and calibration.
Auto Output Functions
The ASC-400 calibrator features two auto output functions: Step and Ramp. The Step function allows for incremental output adjustments, while the Ramp function provides a gradual increase or decrease in output. Both functions require selecting appropriate modes and settings, such as step size and ramp time.
Isolated Measure Modes
The ASC-400 can measure current, voltage, and pressure using isolated inputs. Specific procedures are outlined for measuring mA with external loop supply, using internal loop power, and measuring voltage and pressure. Safety precautions are emphasized for pressure measurements to prevent equipment damage and ensure user safety.
Calibration and Testing
The document details procedures for performing temperature and pressure switch tests, testing input or indicating devices, and calibrating various transmitters (e.g., I/P devices, signal converters). Each procedure involves selecting appropriate modes, connecting the calibrator to the device, and adjusting settings as necessary.
Advanced Calibration Features
The ASC-400 offers advanced features such as scaled current or voltage display and percent error calculation. These features allow for more precise calibration by displaying measurements in desired units and calculating errors as a percentage of the loop span.
Maintenance
Warning: Review safety instructions to avoid electric shock or injury. Only qualified personnel should perform maintenance not covered by the manual. For repairs, contact AMETEK Denmark Service Department.
Returning the Calibrator to Service
If malfunctioning, ensure proper operation as per the manual. For repairs under warranty, refer to the warranty section. If out of warranty, repairs are available for a fixed fee. Include a completed service information form when returning the instrument.
Liability
