Loop calibrator and thermometer model PROVA-135


Loop or loop calibrators are a type of electrical calibrator designed for troubleshooting current loops in the range of 4-20 milliamps. Multicalibrator model PROVA135 is capable of measuring and injecting current to devices without electricity in a loop, as well as simulating the performance of 4-20 mA transmitters. In case of problems such as errors in the measuring equipment, it can be used From a reference device such as current, voltage and frequency calibrator model Prova 135 Pi to the device error.

Prova-135 multipurpose calibrator, in addition to the ability to inject current, voltage and frequency values, simultaneously measures current, voltage and temperature values.

milliampere source model prova-135, a hand-held and portable tool that offers a simple and user-friendly function to the consumer. With this frequency calibrator, a square wave can be obtained in the frequency range of 1 to 20 kHz with the possibility of defining the percentage of DUTY CYCLE. One of the most important applications of this device is to test the brightness of LED lamps by injecting a current in the range of 024mA.

Ability to measure and inject data simultaneously:
Dual loop source mode to test and display the value of DCmA transmitters

Injection and scan of voltage and current in source mode in the following ways:
Auto-Ramp 1% 2% … 100 99% … 2% 1%

Auto-Step 0% 25% 50 75% 100% ...25% 0%

25% or setting the desired percentage to inject current or voltage

It has a dual LCD to display the source and measurement values ​​at the same time
LED brightness test from 0~24mA
Detecting the existence of a fault in the thermocouple
Warning in case of overload, open (mA) or short (V) output.
Output protected against short circuit
Battery percentage indicator
