Manual Overview

The manual for calibrating the Hickok Model 600/600A tube testers provides detailed instructions for testing and adjusting the device to ensure accurate mutual conductance readings. The procedure begins with preparation steps, including removing the tester from its case and setting the mechanical zero on the meter. Calibration involves several tests, including line adjust, shorts test, filament voltage, plate voltage, screen voltage, and grid bias voltage tests. Each test specifies the connections and expected voltage readings, with allowances for minor deviations. The manual emphasizes using a 1000 ohms per volt meter or a modern high impedance voltmeter with shunt resistors to simulate proper loading. For troubleshooting and adjustments, the manual refers to an adjustment chart. Safety precautions are highlighted, warning of the dangers of working with high voltages. The manual also includes tests for mutual conductance reading, plate and screen supply balance, and diode/rectifier tests, providing specific settings and expected outcomes for each.
