Q & A
Temperature data logger specification clarification
16,000 points per channel. Whether 48 hours is possible depends on your logging interval.
Can DTM-319 record 1 sample/second per channel?
Screen updates every 3 seconds; however, it can record 1 time per second for 4 channels. For rising temperature example (1°C/s), the screen may show step-wise values (e.g., 1,1,1,4,4,4), while the logged data captures each second.
DTM-318 vs DTM-319 update frequency
DTM-318 updates ~1.25 times per second per channel. DTM-319 updates once every 3 seconds per channel on screen; logging can be faster as noted above.
Example update pattern (DTM-319 screen):
| T1 | T2 | T3 | T4 | |
|---|---|---|---|---|
| 1 deg C | 1 | 1 | 1 | 1 |
| 2 deg C | 2 | 1 | 1 | 1 |
| 3 deg C | 2 | 3 | 1 | 1 |
| 4 deg C | 2 | 3 | 4 | 1 |
| 5 deg C | 2 | 3 | 4 | 5 |
| 6 deg C | 6 | 3 | 4 | 5 |
