FAQs
Q1: What is the maximum distance the GRZ101 can be used from a Leica robotic total station?
A1: The GRZ101 is typically effective up to 150 meters, depending on the capabilities of the total station model in use.
Q2: Can this prism be used with manual total stations?
A2: While it can physically connect, the GRZ101 is optimized for robotic instruments and may not provide optimal performance with manual total stations.
Q3: Is the prism constant adjustable?
A3: No, the GRZ101 has a fixed prism constant of +30 mm, which must be input correctly into the instrument settings.
Q4: What makes this prism suitable for tight spaces?
A4: Its compact design and lightweight form allow for use in confined areas where standard prisms may not fit or be practical.
Q5: Is the GRZ101 suitable for long-range measurements?
A5: No, it is best suited for short to medium-range applications. For long-range use, larger prisms such as the GRZ122 are recommended.
