As a calibration technician, in every industry that I am exposed to displays a vast number of measuring instruments where pressure instruments, transmitters, electrical equipment and temperature measuring devices are always present.
And if you are thinking regarding the cost for the calibration of each of these instruments, it would be a great amount of money. But since calibration is more important than cost if quality suffers, then it is a good investment for the company.
Why Use Fluke 754?
With all the capabilities that the Fluke 754 does, invested amount of money on this calibrator will be covered in the long run
As an overview, Fluke 754 can calibrate wide numbers of instruments like temperature controllers, transmitters, switches, thermocouples, RTD, pressure gauges and much more that requires a current, voltage or resistance source.
If you are thinking whether to buy or not a Fluke 754 calibrator, a simple justification can be made in order to help you decide. Below is a sample justification:
If the total cost of instruments having it calibrated from an external laboratory is greater than the price of Fluke 754 ( including calibration), then it is time to purchase. With this, you need also to have the knowledge and skills regarding calibration, if not, may be its time to consider having a Calibration tech or officer in your industry.
Above justification is a sample only and as I observe during my internal calibration work, instruments are increasing as your business is progressing.
How to use Fluke 754?
Fluke 754 is a user-friendly calibrator. Once you have powered on the unit, a step by step menu will already appear and easy to follow depending on your requirements and parameter, just in case you can’t follow, a user manual is easily available.
Based on my experience, if you know how to use a multimeter, then using this will be easy for you. The only difference in principle of usage is that a multimeter checks/ test an input from a source like a voltage source or supply while the Fluke 754 has an added source function wherein you can be the supply.
Below are the basic uses and features of Fluke 754:
- Measure and source Thermocouples ( 13 Types)
- Can be use as a multimeter/tester with below ranges:
- Measure and source Current
- Measure and source Resistance
- Measure and source Voltage ( ac and dc) from 0-300 volts
- Measure and source Frequency
- Measure and source pressure ( with set of pressure modules and hand pump)
- As a power supply – It can generate ac and dc voltages up to 15 volts
- Open and short indicator ( continuity)
- As a thermometer read out or display for RTD and thermocouples
Fluke 754 Specifications for Sourcing
For Full specifications, kindly check the user manual.
With the above uses and features of Fluke 754 Documenting Process Calibrator , where a combination of each feature can be used to perform below calibration capabilities:
- Capable to calibrate a thermocouple.
- By simulating temperature directly to the thermocouple connected to an indicator or simply as a readout or display.
- Capable of calibrating a digital thermometer
- A thermometer that usually using a thermocouple probe can also be calibrated through simulation
- Capable of calibrating an RTD ( resistance temperature detector)
- Direct simulation of temperature to an RTD with indicator or as a display
- Capable to calibrate a Pressure gauge
- By using a pressure module and a hand pump, you can calibrate a wide range of pressure gauges
- Capable of calibrating Transmitters ( pressure, temperature, and level)
- A transmitter that is usually program to function in a 4-20 mA current range can be calibrated with a dual display where the converted parameter are seen. For example current to pressure conversion. Fluke 754 is can also read or communicate with a Hart Transmitters ( example: Rosemount).
- Capable of calibrating switches ( pressure and temperature)
- Through simulation of required temperature, current or voltage that triggers a switch.
- Capable to calibrate temperature controllers and overheat protectors
- The input of a Simulated temperature to the overheat protector that have the same principle as the switch.
- Capable of calibrating temperature /Chart recorders
- Most Chart recorders are the same with thermometers except that it has a multiple channels or input for a temperature that are being recorded in a chart. It can be in a manual recording or digital display.
- Capable of calibrating a multimeter/tester with above ranges depending on the acceptable process requirements.
- Since Fluke 754 can source out or simulate Voltage, Current, resistance, and frequency, a limited calibration on a certain multimeter can be accomplished as long as it is accepted by the user that depends on how it is used in the process.
- It can Calibrate or verify a non-contact Tachometer.
- Tachometer can be verified by using a frequency source and a LED (light emitting diode) See this link for this procedure
- It can verify or calibrate a Pressure Safety Valve (PSV) or a Pressure Relief Valve ( PRV).
- And more depending on the needed parameters and specifications of certain instruments that recognize the generated signal of Fluke 754.
With all these features that a fluke 754 can provide, it is very wise to have it as part of our calibration and maintenance program. It has an advance features where you can automate some calibration and measurements but you do not need them if you don’t want to because the basic ones are already enough as long as you understand them. But of course, it is very advantageous if you can apply automation because it makes your job better.
