2. FEATURES
· HOlizontal angle, zenith angle, slope distance, horizontal
distance, height difference, N- and E-coordinates are displayed
by key operation.
· Horizontal distance between two prism points and remote
measurement of objects above and below a prism point are
automatically calculated. A stake-out function by bearing and
distance and N- and E-coordinates is standard.
· Self-diagnostic function. If, for any reason, the SET3 is not
functioning correctly during use, an error code is displayed.
· Angle lesolution can be set to 1" or 5".
· The tilt angle of the vertical axis can be measured by the
intemal sensor and displayed. By referring to the display, the
SET3 can be leveled. The zenith angle is automatically com-
pensated by the. ti It sensor and the compensated angle dis-
played.
· Hmizontal circle can be set to zero in any direction.
· The SET3 automatically switches off 30 minutes after the last
operation to save battery power,
· A RS-232C data-out connector is standard.

Battery charging precautions
To charge the battery, use only the recommended charger,
1) Charge the battery at least once a month if it is not used for
a long time.
2) Charge the battery at a temperature between 50° F to 104° F
(10°C to 40°C),
3) Before using No. 6861-01, set the voltage selector to the
proper voltage, \
4) No. 6860-02 has a breaker switch. Normally the red mark
appears on the breaker. If not, set the red mark in place.
5) When using a car battery, make sure that the polarity is
correct,
6) Make sure that the cigar I ighter has 12 V output and that the
negative terminal is grounded.
7) When charging the battery, first connect it to the battery
charger and then connect the charger to the power supply.
Check that the battery charger light is on, If not switch
power supply off and on again until the light comes on.
8) The battery charger may become warm while charging. This
is normal.
9) Do not charge the battery for any longer than specified.
10) Store the battery in a place where the temperature is between
32° F to 104° F (O°C to 40° C).
11) Battery operating life is shortened at extreme temperatures.
