PORTA features a newly designed friction system for quickly pointing toward the target and tracking it with 360° slow-motion controls. No fumbling with clutches or sectional slow-motion controls! Leave the heavy counterweights with the equatorials: simply balance scopes up to 155mm diameter (and up to 11-lbs/5kg) on the altitude axis and start viewing! Standard Vixen dovetail mounting slot with lock and safety screw is fully SPHINX/GP-compatible. Mounting slot removes to reveal 1/4"-20 and M8-1

• Once set, the temperature is displayed at the center of the top of the measurement screen. • The factory initial of temperature is “1. AUTO”. • Once set, the temperature remains in memory even after the power is turned off. • Temperature correction is based on 15°C. If this instrument is used without correcting the temperature, a distance error per 100m is about -0.1mm per +1°C as a temperature difference from 15°C. A distance error per 100m is about 0.1mm per -1°C as a temperature difference

Turn two leveling screws in an opposite direction mutually and have the bubble of the side of the electronic vial to the center. Make the bubble of the length of the electronic vial to the center by operating the leveling screw of one remainder. Rotate the instrument by 180° and confirm the position of

• Reflector sheet, Target and Prism do not face the instrument. • Reflector sheet, Target and Prism are not correctly sighted. • Measurement range is over in Reflectorless mode. • Sufficient signal does not return by sighting sharp edge etc. at Reflectorless mode. Change the object that has much better reflectivity, or use a reflecting sheet, or wait until the sun activity has weakened. Li-batt.voltage is low. • The Date Clock is powered by Have the lithium battery the built-in lithium battery.

With its unique VISAC (Vixen Sixth-Order Aspheric Cassegrain) primary mirror, the optical system is composed of a concave primary mirror, a convex secondary mirror and a three-element field corrector. Especially noteworthy is its sharpness and flatness at the edge, which far exceeds that of Schmidt- Cassegrain systems of the same aperture. It provides a pinpoint star image of less than 15 microns, even at the edge of its 42mm image circle. The open tube design eliminates the dew problem that is
