| * Each specification is applied to a stable temperature state after a preheating time of 30 minutes*1 A separate bridge box is required *2 In the case of a sensor power supply of DC 2 V, when the positive side of the sensor power supply is +1 V and the negative side is a -1 V sensor power supply DC 5 V, the positive side of the sensor power supply is +2.5 V, the negative side is -2.5 V * 3 Only when online control by PC*4 When the bridge resistance is 350 Ω*5 When FLAT is set, the cutoff frequency is set to about 25 kHz. However, the amplitude ratio specification at the cut-off point does not apply*6 When AUTO is set, the cut-off frequency is set to approximately 1/4 of the set sampling frequency*7 Cut-off frequencies exceeding 5 kHz are excluded. |
