Manual Overview
The Valhalla Model 1248 BCD Dual Limit Comparator is designed to work with Valhalla ohmmeters and power analyzers, providing a “GO” or “NO-GO” decision based on preset limits. It supports binary-coded-decimal (BCD) data inputs and can be powered externally or internally with options for different AC voltages. Troubleshooting involves checking power connections and ensuring the input logic levels are within the specified TTL-compatible range. Error diagnostics are indicated by LEDs: red for out-of-limit conditions and green for in-limit status. Calibration involves setting upper and lower limits using thumbwheel switches. If the upper limit is set lower than the lower limit, undefined results may occur. The comparator interfaces with various Valhalla models using specific data cables, and optional rack mount adapters are available. For board-level issues, refer to detailed circuit descriptions in the manual. For warranty repairs, contact Valhalla Scientific for a return authorization.

Operation
The Valhalla Model 1248 BCD Comparator is designed to work with devices like DVMs and Valhalla ohmmeters that have a binary-coded-decimal (BCD) data output. It is compatible with several Valhalla models, including 2191, 4014, 4020, 4100ATC, 4150ATC, 4165, 4165-1344, 4300B, and 4314. The inputs to the 1248 are TTL compatible. The device reads data from the master unit’s display and compares it to preset limits, providing a “GO” or “NO-GO” decision to reduce operator workload. The standard relay contact closure feature allows for automated sorting processes. The 1248 can be powered externally via the rear panel data input connector or internally using an AC power cord. It requires no warm-up period and can be installed in any convenient location with an ambient temperature not exceeding 50°C.
