- Model 428-PROG Programmable Current Amplifier
The Model 428-PROG Programmable Current Amplifier converts fast, small currents to a voltage, which can be easily digitized or displayed by an oscilloscope, waveform analyzer, or data acquisitionsystem. It uses a sophisticated "feedback current" circuit to achieve both fast rise times and sub-picoamp noise. The gain of the Model 428-PROG is adjustable in decade increments from 103V/A to 1011V/A, with selectable rise times from 2μs to 300ms.

clamp on meter is a combination power analyzer, power quality logger, and clamp meter, and is ideal for monitoring electronic loads.
With the bright color power meter display to analyze the harmonic spectrum, a low-pass filter to remove high frequency noise, and a high EMC immunity design, the Fluke 345 power analyzer is ideal for troubleshooting power quality on switching loads. Additionally, the Hall Effect clamp meter design makes measurement of dc current possible without the need to break the circuit with the power meter. The internal memory of the power analyzer enables long-term power quality logging for analysis of trends or intermittent problems.
Applications
Setup and troubleshoot variable frequency drives and UPS systems - Verify correct operation by measuring key power quality parameters
Harmonics measurements - Uncover harmonic issues that can damage or disrupt critical equipment
Inrush capture - Check start-up current where spurious resets or nuisance circuit breaker tripping occurs
Load studies - Verify electrical system capacity before adding loads

Current must always be measured in our power test systems, of course, but that's just the beginning. Amperage is an important measurement in hundreds of other data acquisitoin applications, too.
We understand that, so we provide more than one choice of current clamp, and also, convenient flexible current sensors (aka Rogowski coils). DEWETRON current sensors output voltage, so they can be used directly with our medium gain voltage input connections. Every current sensor has a phase shift, and this can be offset using the standard sensor database included with DEWESoft! Yes, we thought of that.

Clamp-on current probes or "current clamps" enable the user to measure currents without breaking the electric circuit. Current clamps are designed with jaws that can be opened, placed around the conductor and clamped closed to form a magnetic loop around the conductor.
Current clamps offer a safe, cost-effective, simple and accurate way to take current measurements.
