| Insulation resistance |
The insulation resistance between the instrument output terminal and the enclosure shall be not less than 50MQ. |
| Thermal response time |
When the change of phase step appears,the current output signal of the meter changes to the time which is equivalent to
50%of the step change Generally,T0.5is used to show that the stability time of phase step of the temperature transmitter is
not more than one fifth of the stability time of thermal response r0.5,the thermal response time of a thermocouple
(resistance)is used as the thermal response time of the instrument.When the stability time of phase step of the
temperature transmitter is not more than half of the stability time of thermal response T0.5,the thermal response time of
temperature transmitter is used as the thermal response time of the instrument. |
| Basic error |
The basic error of the instrument should not exceed the synthetic error of the basic error of thermocouple (resistance)and
