The dc ammeter will normally be calibrated at full range in each range 直流电流表一般每程均作全量程校正。
2.
Calibration at full range for dc ammeters with not more than 3 ranges 为不超过三个量程的直流电流表全量程校正。
3.
Model j0407 dc ammeter is suitable for students to measure the current in a dc ciruit in laboratory J0407型直流电流表供学校学生在实验中测量直流电路中的电流用。
4.
Calibration at full range for each additional range on the same dc ammeter ( for ammeters with more than 3 ranges ) 为同一直流电流表每一额外量程全量程校正(只适用于超过三个量程的电流表) 。
