The CM57 Flexible Clamp Meter from FLIR is an ergonomic tool designed to simplify current measurements. Made with a narrow flexible coil clamp, the CM57 lets you take measurements in spaces where a traditional hard jaw clamp meter cannot be used. With Bluetooth communication for remote viewing and data transfer to iOS and Android devices via the FLIR Tools Mobile App, you can analyze and share data quickly.

The NIST (National Institute of Standards and Technology) utilizes traceable reference standards to ensure accuracy. This traceable calibration service is recommended for customers that do not require detailed before and after measurement data.

Q: 5. Can I get a reading from this on the flowers I shoot outside ?? J. Payne

A: Yes this meter will measure incident or reflective light outdoors.

Q: 6. Where is the receptor head? Can't quite tell; it appears to be on the top vs on the front like with the 398. Do you point the receptor head at your subject?

A: Notice the white slide in the front of the meter. If you slide it to the right (the white little bump will cover the sensor) you will be in incident light mode. That is, you should stand where your subject is and point it towards where you will shoot from then take a reading. This is the most accurate method. If you move the white slide to the left (exposing the sensor) you are in the reflective mode. Here you would aim the meter at your subject from your camera position will be. This is how the light meter in a camera works. The differences in value is what your exposure compensation would be if you where using the camera's light meter.

Q: 7. What this meter be good for someone trying to stop using auto mode and learn manual mode on their camera?

A: Possibly. It could help you understand the difference between a reflective reading (what all cameras give you) and an incident reading. (this meter can give you reflective and incident readings. And if you're planning to use studio flash it can be invaluable. But you can learn a lot just by putting your camera in manual mode, put your camera's meter in spot mode, and then just pay attention to how the camera indicates changes in exposure value (EV) when you put the spot on subjects of different brightness. Take pictures using the different readings and see how the overall picture brightness shifts.

Q: 8. Does this meter have a count-down timer?

A: This meter does not have a count down timer.
