Feature Benefit
10:1, 100:1, and 1000:1 reference divider output to 1100 V. Accuracy divides input voltage by 10, 100, 1000, or 10000. Maximum input voltage is 1100 V. Extreme precision to compare direct voltage levels of various sources to a 10 V voltage reference standard like a 1330A, 732B or 732C.
Industry-leading specifications requires no Self-Alignment or Calibration prior to use. Customers no longer need to self-align or calibrate prior to each use. Saves time and money and frustration!
Utilizes a special design network of high precision resistors mounted in a temperature-controlled chamber. Shields divider resistors from outside noise and provides temperature stability to improve performance.
Front panel direct connection to calibrator; divider output connection to DVM for testing; both done with supplied cables. Ease of use, saves time and money.
Internally mounted temperature sensor PT100. Users can connect to front panel and monitor
internal oven.
New special hand-selected resistors and configuration. Lengthy, self-alignment no longer required to create divider network.
Calibration of divider performed directly against a 1330A, 732B or 732C reference. Industry-leading advancement in the DC voltage
divider commercial products which delivers
exceptional performance.
