Selftest Diagnostics and Error Codes

When the instrument is powered up, the entire display lights.

Note

To hold the display fully lit, press and hold the K key, then press R

ON and wait a moment for the instrument to beep. Then release K. The

entire display will now stay on until you press any button; the power-up

sequence then resumes.

Selftest diagnostics are performed each time the instrument is powered up. Any errors

encountered during this initial 4-second period are displayed momentarily. Even in the

presence of an error, the instrument still attempts to complete the selftest routine and

begin normal operation.

An error indicates that a malfunction has occurred and maintenance is required. If you

encounter an error, note the number or letter and consult Table 7-1. See if the instrument

repeats the error. If the problem persists and you intend to repair the instrument yourself,

refer to the Service Manual. Otherwise, package the instrument securely (using the

original container if available.) Then forward the package, postage paid, to the nearest

Fluke/Philips Service Center. Include a description of the problem. Fluke assumes no

responsibility for damage in transit.

Performance Tests

When received, the 2635A Hydra Series II is calibrated and in operating condition. The

following Performance Verification Procedures are provided for acceptance testing upon

initial receipt or to verify correct instrument operation. All tests may be performed in

sequence to verify overall operation, or the tests may be run independently.

If the instrument fails a performance test, calibration adjustment and/or repair is needed.

To perform these tests, you will need a Fluke 5700A Multifunction Calibrator or

equipment meeting the minimum specifications given in Table 7-2.
