Notes:
1. Instruments with ranges other than those listed in the specifications table can be supplied; users must specify such requirements when placing an order, and these details must be confirmed within the contract.
2. Upon user request, a red line can be marked at a specific setpoint on the instrument dial, or the instrument can be manufactured with a red setpoint pointer.
3. The standard operating frequency for these instruments is 50 Hz; however, units configured for 60 Hz or 400 Hz can be manufactured upon user request. Users must specify such requirements when placing an order, and these details must be confirmed within the contract.
4. The (G) model features a black dial face with internal illumination; however, units with a white dial face and internal illumination can also be manufactured upon user request.
5. For instruments intended for special applications, please append the letter "J" after the numerical portion of the model designation (applicable to 240° scale instruments); for example: F96J-AC.
