C4.3.2. Power Supply Module
The lifespan of the electric field condenser used in the power supply module is 8 years
provided that the average temperature of the air intake from the bottom of the module is
45 °C. The power supply module needs to be replaced periodically.
C4.3.3. Replacing Other Parts
The parts described below are not considered parts with limited life spans but may
require replacement depending on their usage and installation environment.

SD Cards
The SD card needs no replacement under normal use. If measurement is executed
continuously over short durations at higher sampling resolutions, the limit on the number
of write operations to the SD card may be exceeded. If the DTSX3000 is used under
such conditions over an extended duration, regular replacement of the SD card is
necessary.

Usage Conditions (*2) Replacement Period
for SD Card
Data Size (*1) Measurement Repetition Period
16000 1 minute 6 years
16000 10 minutes No replacement required
*1: The data size is the distance range divided by the sampling resolution.
For example, assuming 16 km distance range and 1 m sampling resolution, the data size will be 16000.
*2: This table lists typical usage conditions (data size and measurement repetition period combinations). If the usage
condition for your application is not listed above, calculate the ratio of data size to measurement repetition period and
estimate the replacement period using the nearest usage condition listed above.
●
Replacement Preparation
Have on hand a new SD card, as well as the necessary equipment for connecting to the
DTSX3000 from a PC.
●
Replacement Procedure
Follow the procedure below to replace the SD card.
1. After DTSX3000 measurement ends, back up the following data as required:
- LAS/ WITSML files
- measurement settings and
- system settings.
