ES Electronic Specialties 688 True RMS Low Current Clamp Meter

The Electronic Specialties 688 True RMS Low Current Clamp Meter has received mixed reviews from customers. While some users found it useful for diagnosing parasitic battery draw and checking for electrical drain in automotive systems, others were disappointed with its accuracy and readability. One customer mentioned that the meter was not accurate when compared to an ammeter in series with a circuit, stating that the readings were not even close. Another user reported that the meter fluctuated in its measurements when testing low current flow, making it unreliable for precise readings. Additionally, the display was difficult to read at angles other than direct on, causing inconvenience for some users. However, a few customers appreciated the smaller jaws of the meter, as it allowed them to access tight areas that could not be reached with other clamp meters. They also mentioned that using a smaller jumper wire instead of a large ground cable improved the accuracy of their readings when testing for parasitic draw. Overall, the Electronic Specialties 688 True RMS Low Current Clamp Meter offers some convenience and usefulness for certain applications, but its accuracy and readability issues are drawbacks that potential buyers should Consider.
