Measuring Accuracy and Resolution
As described below, under the following operating conditions:
Ambient temperature: 23
±2°C; ambient humidity: 55 ±10% RH; power supply voltage: 90 to 250
VAC (AC power supply)/10 to 32 VDC (the subunit of a DC power supply model only); power
supply frequency: 50/60Hz within
±1% (AC power supply); warm-up time 30 minutes or more;
vibrations and others not affecting instrument operation.
