Notes:
1. Instruments with measurement ranges other than those listed in the specifications table are available upon request; users must specify such requirements when placing an order, and these details must be formally confirmed within the contract.
2. Instruments can be manufactured with a bidirectional indication design, featuring a zero point positioned at the center of the scale.
3. Upon user request, a red line can be marked at a specific setpoint value on the scale, or the instrument can be manufactured with a dedicated red setpoint pointer.
4. Instruments with special specifications can be manufactured to meet user requirements—such as those featuring a single scale with dual readings, or colored dials (e.g., green or red scale lines and characters).
5. The (G) model features a black dial face with internal illumination; alternatively, instruments with a white dial face and internal illumination can be manufactured upon user request.
6. For instruments intended for special applications, please append the suffix "J" immediately following the numerical portion of the model number (***applicable exclusively to 240° instruments); for example: F96J-DC.
