# Interface Model 9840 Intelligent Digital Transducer Indicator Meter

### 📌 ITEM CONDITION & SELLER NOTES

* Condition: Used (Power Tested & Working Display)

* Seller Notes: This unit is in great cosmetic shape with light surface scuffs from a professional laboratory environment. It powers on beautifully, and the bright blue vacuum fluorescent display (VFD) is sharp, clear, and perfectly legible with no faded pixels. All front toggle switches and push buttons are solid and responsive.

* PLEASE NOTE: On the back panel, the small plastic covers/caps for the Fuse holder and the 115V/230V Voltage Selector dial are missing (as pictured). However, the internal dials, housing, and structural components are completely undamaged, and the switches remain fully functional. The device successfully cycles through menus, reading Ch A Max, Peak A, Cal mV/V, and Volt metrics. Power cables and external load cell sensors are not included.

### 🛠️ PRODUCT OVERVIEW
