Description

The TC818A is an integrating analog-to-digital converter (ADC) with a 3-1/2 digit numeric LCD driver, automatic ranging, and single 9V battery operation. The numeric display provides 0.05% resolution and a full set of annunciators that spell out the TC818A's many operating modes.

Automatic range selection of TC818A is provided for both voltage (DC and AC) and ohms (high and low power) measurements. Expensive and bulky mechanical range switches are not required. Five full scale ranges are available, with automatic selection of external volt/ohm attenuators over a 1 to 10,000 range. Two current ranges, 20mA and 200mA, can be manually selected. The auto-range feature can be bypassed, allowing input attenuator selection through a single line input.
