                                    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.
