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. |
