Measurement precautions*
Due to the Due to structural limitations, the output value of the probe may have a deviation of approximately % after one year, which is normal. That is, the standard measurement cycle of the probe is one year.
Since the probe (filter) is very sensitive to humidity changes, the storage environment is very important. When the watch is not used for a long time, be sure to store the probe in a low-humidity environment. For example, store the probe in a dry plastic bag. If the storage method is proper, the life of the probe will be extended a lot
According to the cosine law, under high incident light, the input signal of the probe is in good agreement with the cosine law (compliance degree > %). In the case of degree angle, the degree of compliance is >%. Therefore, the effective angle of incidence is degrees, of course, it is best to be limited to degrees. When calibrating, the incident angle of light should be degrees (vertical)
Storage of the probe The structure of the probe is very precise. When not in use, it must be stored in a dry environment. For example, put the probe and desiccant into a plastic bag and seal it. Only take the probe out when you are using it. The service life of the probe can be extended by using the methods mentioned above. Otherwise, the gain of the probe will be reduced and the calibration period will be shortened. In addition, the desiccant should be replaced regularly.
． Other features: In order to prolong the service life of the battery, this watch has an automatic shutdown function. After about a minute of no operation, the watch will automatically shut down. To disable automatic shutdown, press &R&r during measurement and select the memory recording function
. The computer interface of this meter is output through the R port. The bit data stream output by the connector can be used for the user's special purposes
. The internal zero adjustment in this chapter is a normal zero adjustment step. However, the adjustment range of the &r&r key is only units. If the reading deviation of the internal zero exceeds units, the &r&r key will no longer work
