SHIMPO DRI-series - Manual (Page 18)

18
The DRI incorporates a selectable auto power off feature to protect the life of the batteries. If no buttons are pressed or the display has not
changed for a period of three minutes, the DRI will automatically shut off. This feature is inactive if the DRI is being used with the AC
adapter or if it is in calibration mode. To engage or disengage the auto power off feature:
1. Press the PEAK button while holding down the ON button; the small display will indicate “dSP”.
2. Press the PEAK button two times. The small display will indicate “Off” and the main display will reflect the current setting.
3. Each time the > button is pressed the main display will toggle between “3” and “nonE”.
4. Press the MEMO SET button to store the auto power off selection and exit.
Low Battery Indication
The batteries should be changed when “LO BAT” appears on the display.
NOTE: Parameters and data in memory can be saved if the AC adapter is plugged in and the DRI is left ON before removing the batteries.
Auto Power Off
Calibration
Any remote sensor (LC or TS) can be calibrated in the field. The load cells are very easy to calibrate with metric weights, but the torque
sensors require a “calibration wheel” (please call Shimpo for torque calibration instructions).
Required items for load cell calibration:
• Appropriate calibration weight (see following table)
• Proper attachment for applying the weight to the load cell (either tension or compression)
• Secure mounting stand that will not introduce vibration
Instructions to calibrate a remote load cell are as follows:
1. Mount the load cell to the stand.
2. Secure the attachment to the load cell.
3. Make sure the power on the DRI is turned OFF.
4. Plug in the remote load cell to the DRI
5. While holding down the MEMO SET button, press the ON button and hold until the main display shows “CAL”. The small
display will reflect the two-digit code that corresponds with the load cell (see following calibration table). If the DRI did not
recognize the sensor, the small display will reflect “XXX”.
6. Press the MEMO SET button. The capacity of the load cell will appear on the main display; please move on to step 7. If the
remote sensor was not identified, the display will default to the eight ounce load cell. Use the > button to select the proper code for
the remote sensor (see the following table).
7. Press the MEMO SET button. The small display will show “PLS”. Pressing the > button will toggle the small display “MNS” and
“PLS”. If calibrating under a compression load choose “PLS”. If calibrating under a tension load choose “MNS”.
NOTE: Only one direction calibration is necessary.
8. Press the MEMO SET button. The minimum indicator will appear and the main display will reflect a hexadecimal number that
has no relevance to the user.
9. Confirm that there is no load (except for the attachment) since the DRI is ready for zero point calibration. Press the MEMO SET
button. The small display will exhibit “SCN” and the minimum indicator will blink for about 12 seconds until the maximum
indicator appears.
10. Gently place the proper calibration weight (see the following table) on the load cell and confirm that it is steady. Press the MEMO
SET button to begin full scale calibration. The maximum indicator will flash for about 18 seconds until the small display shows
“ENd”.
11. “ERR” will appear on the display if the calibration failed. Turn the power off and repeat the entire procedure.
12. After “ENd” appears, press the OFF button to end the calibration process.
