3.3 Set up the target Type
The ZTS-320(R) Total Station has three options of reflectors:
prism, non-prism and reflector board.ZTS-320, however, has
only two: prism and reflector board. You may set up their favored
type with star key(
3.4 Set up the Reflecting Prism Constant.
As a prism is selected as a reflector, a prism constant should
be set before any measurement. If the constant is entered and set,
it is saved and will not be erased after switching off the
instrument. After pressing „parameters‟ key under star key(

)
mode, a dialogue box would appear as followed.
Press the soft key “Enter”to move inserter down to the
„Para.‟ column of prism constant.
3.5 Signal
The function of signal is to display the intensity of signal of
EDM (Electrical Distance Measurement). It can help achieve
ideal aiming result under poor conditions. If it is too difficult to be
found, using signal can easily aim at the target. Continuing with
the explained operation in 3.4, you may press „Signal‟ and the
intensity of signal is displayed in the „Signal‟ column above. The
minimum measurable intensity should be 1. Being less than 1
indicates that the target cannot be aimed and measured. You can
press any other keys to quit signal detection.
3.6 Set up the Atmospheric Correction
When measuring distances, the measured value can be
influenced by the atmosphere. In order to reduce the influence, a
atmospheric correction parameter is needed.
Temperature: the surrounding atmospheric temperature
Atmospheric pressure: the surrounding atmospheric
pressure
PPM: the calculated and predicted atmospheric correction
