2. You should be able to move your eye up and down or left and right without
seeing the target shift with respect to the crosshairs.
3. If there is parallax, readjust the eyepiece.
Always remove any parallax before operation to assure accurate measurements.
Aiming At The Target
Loosen the clamps and point at the target using the targeting sights located above and below
the telescope. (Fig .11)
Allow some space between your eye and the targeting sight.
MEASUREMENT
Power
1. Turn the power on. All segments of the display will light for 2 seconds. (Fig 12)
2. The vertical reading will then be shown as "SER", which stands for "SET" (Fig .13)
3. Rotate the telescope to set the vertical "0" point. This is done to cause the zero pointer to pass
a sensor and start vertical angle measurement. (Fig .14)
4. Check battery power:
Full, partial and low power,measurement is possible. No power, no measurement possible;
replace the batteries.(Fig .15)
Note: Battery operating time will vary depending on type and brand and operating
temperature. Be sure to keep an extra set of alkaline type AA batteries in the carrying
case. For any other questions about the batteries, see section 4.
Measuring Horizontal Angles (FIG 16)
1. Aim at target "A"
2. Press "0SET" key to zero out horizontal angle reading, HR 0°00'00".
3. Aim at second target, "B", and the angle between "A" and "B" will be displayed, HR 30°15'00".
"HR" shown on the display means that the horizontal angle reading increases as you
turn the instrument clockwise.
"H L" shown on the display means that the horizontal angle reading increases as you turn the
instrument counterclockwise.
