V • Hz (energized for 1 minute)
Current under overload: Steady state 15 mA or less, transient state 0.8 A or less
• The DT4910 Thermocouples (K) are used.
• The accuracy does not include the error of the DT4910 Thermocouples (K).
• Display update rate: 1 time/s (including disconnection check)
*1: In an environment where the temperature of the instrument is ±1°C and
stable, the accuracy is specied.
Standard contact temperature compensation stability time: 120 minutes (When
the instrument environmental temperature changes quickly from 50°C to 23°C
(122.0°F to 73.4°F).)
*2: The °F display is activated using a special instrument operation.
