*1 Conforms to requirements for Class AA of JIS C 1609-1: 2006 for all items except cosine response (f²).
*2 Although measurements below 1.00 lx are possible, they may not be stable due to the effects of electrical noise.
Notes regarding mini receptors and waterproof mini receptors
*Do not touch the cable during measurements. Doing so may result in unstable measurement values.
*Secure the cable during measurements. Failure to do so may result in unstable measurement values |
