Note: (b) With the “user threshold” setting set to minimum. For other settings, the spec is for >10% of full scale or greater than twice the "user threshold", whichever is greater. The user threshold is available with Nova II, Vega, StarLite or Juno. For other meters, the threshold is set to minimum and the linearity spec is >10% of full scale. The PD-C series will only operate with Nova or Orion meters with an additional adapter Ophir P/N 7Z08272 (see page 77). The adapter can introduce up to 1% additional measurement error.
The user threshold feature allows adjustment of the internal threshold up to 25% of full scale if desired to avoid false triggering in noisy environments. For highest accuracy, it is recommended to zero the sensor against the meter the first time it is used with a particular meter. For further information, see the FAQs on our Website.
