When data is recorded by external sampling, the amplitude of measured voltage and temperature is large or unstable.
If the AC line filter is set to Disable (Off) when external sampling is enabled (On), set it to Enabled (On) and measure at an external sampling interval higher than the fastest interval at which the digital filter is enabled.
The fastest interval is shown in the table below.
Measurement CH * | Fastest interval | |
Digital filter “Off” | Digital filter “On” | |
1ch | 10ms | 200ms |
2ch | 20ms | 500ms |
3~5ch | 50ms | 1s |
6~10ch | 100ms | 1s |
11~20ch | 200ms | 2s |
21~50ch | 500ms | 5s |
51~100ch | 1s | 10s |
101~200ch | 2s | 20s |
* The number of measurement channels is the number of channels for which the input setting is set other than Off.
