Unsuitable Condition ERROR!! EDM ERROR 04 -05, 34-39, 50-53 ERROR!! ETH ERROR 7076 ERROR!! ETH ERROR 19 ERROR S DATA of EDM ERROR P DATA of EDM ERROR ETH DATA Meaning Displayed when the instrument is tilted beyond the vertical compensation range (±3') in case 1 axis or 2 axis automatic compensation is selected. This message may be temporarily displayed if the instrument is turned too fast. The input data exceeds the allowable range. The distance is measured by Prism at Reflector sheet mode, and the distance is over than 1000m. The distance is measured by Prism or Reflector sheet at Reflectorless mode, and the distance is over than 200m. The measurement distance is less than 1.5m at Reflector sheet mode. The measurement distance is less than 1.5m at Prism mode. Under too strong sun light. Unstable light value owing to shimmer or obstacles. Reflector sheet, Target and Prism do not face the instrument. Reflector sheet, Target and Prism are not correctly sighted. Measurement range is over at Reflectorless mode. Sufficient signal does not return by sighting sharp edge etc. at Reflectorless mode. Distance measurement system problem Angle measurement system problem Memory problem Problem of the internal EDM parameters Problem of the internal ETH parameters What to do Re-level the instrument. Repair is needed if the message is displayed when it is properly leveled. Press the [ESC] key and enter the correct data. Select the correct target mode. Select a longer point, or use a tape measure. Change the object that has much better reflectivity, or use a reflecting sheet, or wait until the sun activity has weakened. Turn the power off, and then turn on again. Repair is needed when the message appears consistently. PENTAX R-300 (p65-88) 10/30/02 11:11 AM Page 80 13 APPENDIX 13-2 Atmospheric Correction The speed at which light travels through the air varies depending on the temperature and atmospheric pressure. The R-100 series is designed to measure distances at the speed of light in order to measure accurately, Atmospheric Correction needs to be used. The instrument is designed to correct for weather conditions automatically if the temperature and pressure are input. Correction is then carried out based on the following formula.

When the actual pressure is 1013 hPa (760 mmHg) and the temperature is 25°C, conducting the measurement with the temperature left at 15°C will result in the measurement being short by 0.9 mm per 100 meters.
