No target readings in PDA.
Target LEDs illuminated
(means target is detecting
laser)
•
Check radio receiver battery. Plug in A/C adapter to ensure it has power.
•
Ensure “check box” to the left of the display window in Read9 (see
manual) is checked for each target.
•
Ensure channel setting (system ID) on A-1519/1520 matches the setting in
PDA (see Read9 Manual).
•
Ensure target ID on A-1519/1520 is set to 1-4 for first screen or 5-8 in
second screen in Read9.
•
Target is too close to laser (target LED’s will blink).
•
Check for reflections.
•
Check for strobe lights and rotary lights.
•
Check for excess background light (normally target LEDs will blink).
•
Plug target into computer via USB cable and open Target Utility software.
If software shows reading, then there is probably a problem with the radio.
•
Ensure PDA has same radio frequency as target (900 MHz or 2.4 GHz).
•
Reset target (use paper clip in hole near Target ID/Channel Selector
Panel).
•
Laser could be hitting too low or high on target window (it should be near
the window). It’s possible for the laser to activate the auto wake up feature
of target, but not enough of the beam is hitting the PSD (target sensor) to
get a reading.

No target readings in
software. Target LED

•
Ensure A-910 radio base station is connected to USB port.
•
Ensure the correct COM port is selected for the USB bridge controller –
see Windows Device Manager (must be lower than COM10).
•
Check Device Manager in Windows Control Panel. Set COM port for
USB bridge controller lower than COM10.
•
Ensure the correct target ID is chosen in Machine Tool Geometry or
Read8 software.
•
Ensure channel setting (system ID) on A-1519/1520 matches the setting in
A-910 (see the Target Utility Manual).
•
Ensure SND/RC LEDs on A-910 are blinking (see the Target Utility
Manual).
•
Ensure ACTUAL TARGETS (RADIO in Plane5) is selected in Read8,
Plane5 or Machine Tool Geometry software.
•
Ensure antenna is connected to A-910.
•
Target may be too close to laser (target LED’s will blink).
•
Check for excess background light (normally target LEDs will blink).
•
Ensure A-910 radio base station has same radio frequency as target (900
MHz or 2.4 GHz).
•
Laser could be hitting too low or high on target window (it should be near
the window). It’s possible for the laser to activate the auto wake up
feature of target, but not enough of the beam is hitting the PSD (target
sensor) to get a reading.

target display – PDA
•
Radio communication is working, but the target does not “see’ the laser.
Ensure laser beam is not blocked.
Ensure laser beam is bright.
Check laser power supply, especially if using a battery pack.

Cannot see level vials
•
Turn on level light switch.
•
Turn on master power switch.
•
Check power supply connection.
