Line Regulation
The outputs will change no more than 0.05 ppm for any 10% line voltage change or for
the entire operating range of the battery.
Output Protection
All outputs can be shorted indefinitely without damage to the instrument. The 10V
output can withstand voltages from other sources as follows:
1. For voltages ≤ 220V dc, the unit is protected for up to 50 mA continuous current.
2. For voltage ≤ 1100V dc, the unit is protected for up to 25 mA continuous current or
up to 0.6 joules for short periods of time.

Line Power Requirements
Line voltage is accepted in the two ranges 90 to 132V and 180 to 264V, at 47 to 63 Hz as
shown in the table below. AC line current at 120V ac is 0.13A.
732B Line Voltage Setting Line Voltage Accepted Frequency Accepted
100V 90 to 110V 47 to 63 Hz
120V 108 to 132V 47 to 63 Hz
220V 180 to 235V 47 to 63 Hz
240V 225 to 264V 47 to 63 Hz
Battery Operation
When fully charged, the internal batteries will operate the 732B for a minimum of 72
hours at 23 ±5°C, with 0 to 0.1 mA current drain at the 10V output. Model 732B-7001
contains the same battery and charger as Model 732B.
