*1 Operating conditions: Temperature 23 ± 3°C, humidity 20 to 80% RH, power voltage rating ±5%, positioned horizontally.
Refer to Yokogawa’s pressure standard.
*2 Measurement mode can be switched between normal, medium-speed, and high-speed on the 76738 only.
*3 Data output rate via communications is the same as the display update rate.
*4 Measurement conditions of response time:
• Time from the start of change until the value settles within ±1% of the convergence value.
• Release from full scale value to atmospheric pressure. (Input section is no load condition. From 0 to atmospheric pressure
for the absolute pressure model.)
• Measure using D/A output.
