| Recording interval | Nine options including 1, 2, 4, 6, 15, 30, 60, 120 and 240 s can be selected. |
| Storage length (continuous record without power-off) | 24 days (1 s interval) – 5825 days (240 s interval)
Calculation formula: recorded time (day) (! Note: For calculation of channel number, the program divides the channel number into five options, namely 4, 8, 16, 32 and 64, and the bigger figure should be regarded as the channel number for calculation in case the channel number of the instrument is between the said two options. For example: If the channel number of the instrument is 12, then 16 should be adopted in the formula.) |
| Alarm Output Function | Max 18 channel alarm output, normally open relay contact output, where the contact capacity is 1 A/250 VAC (resistive load)
(! Note: Please do not carry load directly in case the load exceeds the contact capacity of relay.) |
