Users Manual

100,000, 30,000, and 3,000 selectable count resolution, with display reading speeds of 2.5, 5, and 20 readings per second (rps), respectively.

Built-in self-tests with closed-case calibration (no internal calibration adjustments).

Options and Accessories

Two options are available. These options can be installed in the meter at the factory or by the customer on site:

The IEEE-488 Interface (Option -O5K) provides full programmability, and automated calibration. The IEEE-488 computer interface command set is identical to the RS-232 interface commands wherever possible.

The Battery Kit (Option -01 K) consists of a rechargeable, 8 V, lead-acid battery, with battery bracket and charger assembly. The battery has a typical operating time of eight hours and is fully operable at ambient temperatures between 0 and 50 °C. For complete battery specifications, refer to Appendix A.

Available accessories are listed and described in Table 1-1.
