S type thermocouple input:
range of measure temperature: -50 °C…1768 °C
basic error: 0.1 % of the range
Additional errors:
- compensation of temperature changes of reference joints ≤ ±1 °C
- compensation of lead resistance changes
at lead resistance change, < 10 Ω
≤ ±0.5 °C
at lead resistance change, < 20 Ω
≤ ±1 °C
- from ambient temperature changes ≤ ±(0.1 % of the range / 10 K)
Averaging time:
≤0.5 s (default)
Duty cycle/activity timers:
resolution: 1 s
Range of alarm outputs
(according to the TTL levels according to EIA
