The Ametek CSC100 is engineered for instrument loop calibrations and is
specifically manufactured for 4 to 20 mA loops; however this versatile
instrument offers much more than than.The CSC100 can source and read
current and voltage; including millivolts. It can also be used as a
signal simulator to test your transmitters without the need for actual
operation. The CSC100 also offers features such as an auto-stepping function and fuse-less protection. These handy time savers are combined in a package offering an easy-to-read, two line display, and an intuitive keypad with a knob for fine adjustments. The CSC100 signal calibrator offers you the accuracy and features that you need in a convenient, compact, and easy-to-use package. The CSC100 is a signal loop calibrator; it is designed to source and read voltage and current for loop signal calibration. This unit is a handy calibrator that can meet applications such as simu-lating a transmitter in a loop, measuring voltage, and checking output mA or mV levels. The CSC100 is not simply a calibrator but an effective troubles-hooting and test device. This versatile instrument is dedicated to loop calibration but that does not mean that this instrument is made to do only one thing. |

Voltage modes The CSC100 offers the ability to source and read voltage. There is a VDC and mVDC scale to meet multiple applications. This allows the unit to function as a source to indicators and to other functions that are driven by voltage signals. The CSC100 can be used to drive a meter to specific setpoints for validation of operation without the need for other equipment. It is also pos-sible to take a quick voltage measurement. Current modes The CSC100 offers four different functions in the current mode. It can source current to inject a signal into a loop or simulate current and it may act as the transmitter in the loop to drive other functions or remote indications. The unit can simply be used to measure current. Additionally the CSC100 can power and read the instrument at the same time; providing that the unit under test is removed from the loop while under test or is removed from the system. Setpoint operation The CSC100 offers a one button feature that is missing on many other loop calibrators. When it is sourcing or simulating current, the 25% key can be used to step in increments through a test or calibration. The calibrator will output mA values corresponding to 25% steps for a 4 to 20 mA transmitter. Just connect the unit and set it for current simulation or sourcing and press the key, the value will be 8 mA or 25%. Then, continue to use the function to step up through to 100% of the reading. It is possible to have the manual control of the test, but the calibrator takes care of the calculation for your test points. Automatic operation In addition to the manual stepping with the 25% key, the CSC100 takes functionality one step further and offers an automatic option. This is again a one button solution utilizing the AUTO key. Set the unit up to simulate or source current and then press the AUTO key. This will activate the auto stepping feature and the calibrator will step through 25, 50, 75, and 100% values for a 4 to 20 mA device. These steps occur once every 5 seconds. If a faster test is needed the AUTO key may be pressed again to activate fast ramping. Auto shutdown The CSC100G offers an automatic shutdown feature. This power saving feature turns the calibrator off after it has been idle for a specified period of time. The time delay is factory set to 30 minutes, however the time nay be adjusted. Large display The CSC100-G features a large two-line display. The upper line shows the measured or sourced voltage or current value. The second line is available in the mA modes to show the percentage of 4 to 20 mA. The display also features several icons to allow for quick recognition of the status of the unit. |
