Note: (b) For >7% (>10% for PE9-ES-C) of full scale, with the "user threshold" setting set to minimum. For other settings, the spec is for >7%/>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 PE-C series will only operate
with Nova or Orion meters with an additional adapter Ophir P/N 7Z08272 (see page 79). 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. The user threshold setting represents
the approximate minimum energy for pulse widths below ~50% of the pulse width setting. For longer pulse widths, the actual minimum may be higher. 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.
Note: (c) A shock absorbing mounting post is available for situations in which sensor is mounted on a surface subject to shock or vibration. This can prevent false triggering ａnd allow working
at lower minimum energies (see accessory page 79 for mounting post).
Note: (d) With the Laserstar, Pulsar, USBI, Quasar ａnd Nova/Orion with adapter, only 2 out of 3 pulse widths settings are available; the 1µs (displayed as “10µs”) ａnd the 2µs (displayed as “20µs”).
