Page 17: Calibration Frequency
Although there is no particular calibration frequency that is correct for all applications, a calibration frequency of every 3 months is adequate for most H S transmitter applications. Unless experience in a particular application dictates otherwise, RKI Instruments, Inc. recommends a calibration frequency of every 3 months for the H S transmitter. -
