Informazioni
GENERAL
The Model 515A Megohm Bridge is an instrument for measuring
resistance from 10⁴ ohms to 10¹⁵ ohms with a limit of error
from .05 to 1%. It comprises a solid-state, guarded,
electrometer null detector; an ultra-stable,
highly-regulated dc Voltage Source, and a Wheatstone bridge,
1-2. FEATURES.
a. Accuracy Verification: Accuracy is traceable to the
National Bureau of Standards by use of the Model 5155
resistance standards available as an optional accessory.
b. Selectable Bridge Voltage: An internal voltage
source spans a range from 1 to 110 volts in 1-volt steps.
c. Shielded Compartment: Connection to the bridge is made
using a guarded terminal in the shielded compartment which
minimizes noise pickup.
d. Standardize Mode: This mode can be selected for quick
calibration of bridge elements to correct for slight changes
in the standard high megohm resistors.
e. Guard Leakage Check: A quick self check of the guard to
ground resistance can be made using test jacks on the front
panel (inside the measuring compartment .
