Commissioning
Power supply
- Charging the Li-ion rechargeable battery
The Li-ion rechargeable battery is charged using the mains adapter provided.
Alternatively, the battery can be charged using the USB connection cable
provided, as well as the M12 RS485 connection. The charging time depends on
the maximum charging current of the source. Remaining connected to the mains
adapter for a long period of time will not damage the Li-ion rechargeable
battery.
Other power sources can damage the measuring tool!
Before using the unit for the first time, ensure that the rechargeable battery
is fully charged!
Charging time: approx. 3 hours.
- After 1 hour, the Li-ion rechargeable battery will be charged to approx. 80%.
- Charging temperature range: 0 °C – 40 °C
- Do not allow the Li-ion rechargeable battery to become fully discharged.
- The performance of the Li-ion rechargeable battery is dependant on temperature.
LCD indicator:
- Symbol not displayed – rechargeable battery is charged
- Low battery level
- If connected to the mains – rechargeable battery is being charged
- If connected to the mains – rechargeable battery is fully charged
4.2 M12 socket pin assignment
When charging via the M12 socket, observe the following:
-
Correct polarity
-
Voltage:
+ 4.75 V (DC) … +5.25 V (DC) -
Charging current:
100 mA … 2000 mA
Connection cable
- Pin assignment for the enclosed connection cable to the M12 socket
Switching the unit on
- After switching on with the “ON/OFF” button, an automatic test is carried out. All the display’s segments are shown.
- After the end of the test, the version number S x.xx of the software is briefly displayed and the automatic switch-off time (Auto OFF) is shown.
Functions
Visual guidance
- Triangles representing the inclination indicate the position of the digital protractor in relation to the horizontal or vertical axis.
- The 2 “centre display” bars indicate the precise position at which the vertical or horizontal axis is reached.
- Display showing direction of inclination
Acoustic guidance
- The acoustic guidance is selected via the “FUNC” button. The tone sequence speeds up as the 0°, 90°, 180° and 270° positions are approached in a range of +/- 2°.
- A change in the pitch indicates that these positions have been exceeded.
- A continuous signal tone confirms the precise point at which 0°, 90°,180° and 270° are reached.
- This function is not active in interface mode.
Automatic display inversion
The display is inverted for overhead measurements so that it is always legible.
Setting the “MODE” unit of measurement
- The unit of measurement is set by pressing the “MODE” button several times.
- The set unit of measurement is retained after the unit is switched off.
Locking the measurement with “HOLD”
The current measurement can be locked by pressing the “HOLD” button. The
relevant inclination triangle and the bars flash. The “Hold” symbol is
displayed continuously. The measurement is displayed continuously.
The locked measurement is deleted by pressing the “HOLD” button again or
switching the unit off.
Freely selectable zero position “REF”
- The “REF” button can be used to select any set angle as 0° reference. The angle details now displayed relate to this reference angle. The displayed valueflashes with this setting.
- The reference angle value is displayed for 3 seconds by briefly pressing the “REF” button.
- The reference angle is deleted by:
- Pressing and holding (≥ 3 sec) the “REF” button If the keylock is active, this must be disabled first.
- Switching off
- The automatic switch-off function
The zero position then refers back to the original setting.
The alignment selected for the digital protractor must not be changed during the reference function, as this could lead to a display error.
“FUNC” button settings
-
The user can switch between the different setting options by repeatedly pressing the “FUNC” button. While the display is flashing, the selected function can be confirmed with the “ENTER” button. If no button is pressed, the “FUNC” menu closes after a short time.
-
The “ON/OFF”, “FUNC” and “ENTER” buttons are always active.
-
With battery operation: switch between 0.2 and 2 hours. The unit is permanently on when connected to an external power supply.
The baud rate can be set from 1200 – 19,200 Bd.
- The Analytics evaluation software can only be connected with a baud rate of 9600 Bd.
Checking the measuring tool
Accuracy check
-
To prevent measuring errors, the accuracy of the measuring tool must be checked at regular intervals; for example, each time before beginning work, or after a heavy impact or extreme fluctuations in temperature.
-
Step
Place the unit with the lower measuring sole on as horizon-tal a surface as possible (e.g. a table) with the display side facing the user. Determine the measurement. -
Step
Turn the unit by 180° in the same position. -
Step
The rear of the unit is now facing the user.
Calculating the error:
0.00° − display Œ = A
360.00° − display Ž = B
If A+B is greater than ± 0.05°, the tool must be recalibrated.
-
Calibration -– Adjustment
By pressing the “CAL/ADJ” button repeatedly, the user can switch between CAL2P = calibration in relation to the meas-uring sole and ADJ4P = sensor adjustment. The selected function is confirmed by pressing the “ENTER” button.
Calibration
-
Step: Once “Calibration” has been selected with the “CAL/ADJ” button, confirm by pressing “Enter”.
Display: CAL2P -
Step:
Place the unit with the lower measuring sole on as horizontal a surface as possible (e.g. a table) with the display side facing the user. Calibration is started by pressing the
“CAL/ADJ” button. “CAL” flashes in the display.
Display: CAL2
Calibration step 2 successfully completed -
Step:
Turn the unit by 180° in the same position. -
Step:
The rear of the unit is now facing the user. The second calibration is started by pressing the “CAL/ADJ” button.
“CAL” flashes in the display.
“rdy” display: Calibration completed successfully!
Adjusting the sensor
The sensor must be adjusted if the “temperature” or “Adj.” symbols are shown in the display.
-
All 4 planes are adjusted during the sensor adjustment.
-
The sensor can only be adjusted if the two black bars appear on the display (in the range of 0°, 90°, 180° and 270°).
-
“ADJ” flashes during sensor adjustment of the respective plane.
-
Planes that have not been adjusted are not displayed. Successfully adjusted planes are permanently indicated in the display. -
Step 1:
Once “Sensor adjustment” has been selected with the
“CAL/ADJ” button, confirm by pressing “Enter”.
Display: ADJ4P -
Step 2:
Hold the unit in plane 1.
Press the “CAL/ADJ” buttons.
If the plane has been adjusted successfully, it is displayed permanently. -
Step 3:
Turn the unit by 90° to plane 2.
Press the “CAL/ADJ” button.
If the plane has been adjusted successfully, it is displayed permanently. -
Step 4:
Turn the unit by 90° to plane 3.
Press the “CAL/ADJ” button.
If the plane has been adjusted successfully, it is displayed permanently. -
Step 5:
Turn the unit by 90° to plane 4.
Press the “CAL/ADJ” button.
“rdy” display: Sensor adjustment completed successfully!
Error messages
The sensor must be adjusted if the “temperature” or “ADJ” symbols are shown in
the display.
Display: Error
The measuring unit must not be moved or subjected to vi-brations during the
calibration/sensor adjustment. This can lead to measurement errors.
Display:
Measuring unit inclination around longitudinal axis > 10°
- Display: mains connection/battery symbol flashes Temperature too high or too low to operate the rechargea-ble battery
- Display: mains connection/battery symbol flashes quickly Charging voltage too high or too low
- Display: only the lightning symbol flashes quickly Rechargeable battery is faulty
Data transfer
protocol
The transmission protocol is configured in accordance with the MODBUS
standard.
Characterformat:| 1 start bit, 8 data bits, 2 stop bits, no parity
Baud rate:| Default setting: 9600 Bd
Possible: 1200 Bd … 19,200 Bd
Idle period:| at least 3.5 characters between two messages

than 10° during the measurement, the TECH 1000 DP supplies the value FFFF h (
65535 d ).
PRINT MODE:
A query is sent from the PC to the measuring unit. If the “PRINT” button has not yet been pressed, the TECH 1000 DP supplies the value CCCC h ( 52428 d ).
Otherwise, the TECH 1000 DP supplies the angle at the time the button was pressed.
If the inclination of the measuring unit in the longitudinal axis is greater than 10° during the measurement, the TECH 1000 DP supplies the value FFFF h ( 65535 d ).
