Notes:
1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +20 ℃ +68 ℉.
2) The display range (measurement range) is switched automatically when the measurement distance setting is changed at the controller.
3) F.S. is 2,000 V (-1,000 V to 1,000 V) for the ±1 kV range mode and 4,000 V (-2,000 V to 2,000 V) for the ±2 kV range mode.
4) The values given are for when the measured potential is ±200 V or less in the ±1 kV range mode and ±400 V or less in the ±2 kV range mode. If the measured potentials are outside these values, the values will be equal to the displayed values ±5 %.
5) The values given are for when the measured potential is ±200 V or less in the ±1 kV range mode and ±400 V or less in the ±2 kV range mode. If the measured potentials are outside these values, the values will be 0.5 %/℃ of the displayed values.
6) In order to satisfy the linearity specifications for the analog output, do not use the judgment output.
7) This product is CE compliant and complies with EMC directives. EN 61000-6-2 is the applicable standard that covers immunities relating to use of this product, but in order to comply with this standard, the following conditions must be satisfied.
- The controller must be connected to the power supply at a distance of less than 10 m 32.808 ft.
- Install the ferrite core (accessory) to the cable approximately 30 mm 1.181 in away from the sensor head (EF-S1HS).
