1-2. The Fluke Model 732A is a highly stable, rugged, and transportable, solid state, dc voltage reference standard. The 732A has 10V, 1.018V and IV outputs. These outputs are available on front panel binding posts. The calibration adjustments for the IOV, 1.018V and IV outputs are accessible through the front panel. A nonconducting adjustment tool is supplied with the unit for this purpose. 1 -3. All outputs of the 732A can be shorted indefinitely without damage. Recovery occurs in less than 2 minutes after the short is removed, with no loss of stability. 1-4. The stability and accuracy of the 732A allow direct substitution for saturated standard cells in many applications. The stability specification of 0.5 ppm for 30 days is achieved by enclosing the reference Amplifier and output divider of the 732A in a high thermal gain oven. Full accuracy is attained over the specified ambient temperature range of 23 ± 5°C (64.4 to 82,4<1F). Variations in oven temperature may be monitored externally via the OVEN TEMP THERMISTOR terminals on the front panel. 1-5. The 732A may be powered from ac line power, an internal rechargeable battery, or an external low voltage ac or dc source. The 732A is designed to be powered continuously, including during storage or shipment. The back-up battery will continue to operate the 732A for up to 12 hours. Either line or battery power may be removed without affecting the output. The battery is kept charged by an internal battery charger when operating from ac line power, or from the external low voltage ac or dc source. 1“6. Various front panel LEDs (indicators) provide a continuous indication of the operating status of the 732A. The AC PWR indicator illuminates in the presence of ac line power. The BTRY CHG indicator is on steadily for normal charging activity, and is off when the battery is charged. The IN CAL indicator monitors the’ input voltage to the Reference and Oven. Should this voltage fall below that needed to keep the 732A operational, the IN CAL indicator is latched off, indicating a loss of power and standardization, Once power is restored and standardization toäs been verified, the IN CAL indicator can be reset. 1-7. The 732A may be used on the bench or rack mounted* The 732A is a half-rack width instrument and occupies 4 standard 1.75 inch rack spaces. Accessories for the 732A are listed in Table 1-1 and described in more detail in Section 6 of this manual. There are no options available for the 732A.
