Page 7: Chapter 1 - General Information
Instrument Identification Valhalla Scientific instruments are identified by a two part serial number. The Serial Tag is located on the rear or bottom of the instrument. The number is in a form of 00-0000. The first two digits, called the serial number prefix, indicate the model. -
Page 8: Chapter 2 - Unpacking And Installing
If the unit fails to operate or fails to meet the performance specifications of Chapter 3, notify the carrier's agent and the nearest Valhalla Sales Office. Retain the shipping carton for the carrier's inspection. DO NOT return equipment to Valhalla Scientific or any of its sales offices prior to obtaining authorization to do so. -

Chapter 4 – Optional Equipment Available Options Listed below are the options available for use with the Alpha 4314 Series Digital Igniter Testers. Option A: Battery Charger Option "A" is an AC/DC converter that converts 115VAC line voltage to 6VDC at 300mA. One charger is provided as a standard accessory with every Alpha 4314. -
Page 12: Option Mp-3: Kelvin Micro-Probes
Option MP-3: Kelvin Micro-Probes Option "MP-1" is a 48" shielded lead set (dual banana), handheld pencil type, terminated in spring loaded steel tips with .08" separation (1 amp max.). Special orders or modified versions available upon request. Option MP-4/MP-5: Surface Probes These probes permit rapid, repeatable bonding testing on a variety of screened or flat surfaces. -
Page 13: Chapter 5 - Operations
Chapter 5 - Operations General This section of the manual contains complete operating instructions for the Alpha 4314 Series Digital Igniter Testers. A description of the front panel controls, connection instructions, and the theory behind 4-wire resistance measurement is discussed in this section. -
Page 14: 4-Wire Resistance Measurement
4-Wire Resistance Measurement The four-terminal configuration of the Alpha 4314 eliminates errors normally caused by test lead and contact resistances. In many applications the contact resistance can exceed the value of the load by several orders of magnitude. The Alpha 4314 bypasses this potential error source by providing two terminals of constant current and an additional two terminals for high impedance voltage measurement. -
Page 15: Connections
LED marker on the Alpha 4314 front panel. Every Alpha 4314 Series Igniter Tester is thoroughly tested before it leaves the factory. These tests include a failsafe test that simulates a "worst case" failure condition. The resulting output current is recorded and provided on the Certificate of Calibration included with every Alpha 4314. -
Page 16: Battery Monitoring Circuitry
Battery Monitoring Circuitry A standard feature of Alpha 4314 is a circuit that monitors the output voltage of the internal battery supply. The Battery Status LED for this feature is located to the far left of the display window. • A green Battery Status LED indicate that the batteries are charged and the device can be used. -
Page 17: Chapter 6 - Troubleshooting
Use only the specified component or its exact equivalent. Spare parts can be ordered from your nearest Valhalla Scientific Service Center or directly from the factory by referring to the Valhalla Stock Number. -
Page 18: Chapter 7 - Routine Maintenance
Chapter 7 - Routine Maintenance General This section of the manual contains routine maintenance information regarding the Valhalla Scientific Model Alpha 4314 Digital Igniter Testers. Calibration should be performed regularly to ensure continued instrument accuracy. The recommended calibration interval is one year. -
Page 19: Calibration Procedure
Calibration Procedure VOLTAGE SENSE ADJUSTMENTS for STANDARD CURRENT MODELS Connection: Apply voltage at Voltage sense Input and short current source and Voltage sense negative Terminals. And select second Range 1. Apply to the Voltage Sense 0.000mV using a precision power supply. 2. -
Page 20: Resistance Adjustments
RESISTANCE ADJUSTMENTS 1. Select 2 range. 2. Connect a standard resistor ½ scale of the selected range. Example: If the 200Ω range is selected connect to a 100Ω standard resistor. 3. Adjust R15 for a display reading of “10000” (Decimal point unimportant). 4. -
Page 21: Low Battery & Power-Up Check
The rechargeable NiMH batteries used in the Alpha 4314 are very durable and should provide years of trouble-free operation. As with all batteries, a replacement will eventually be necessary. Batteries may be ordered from Valhalla Scientific as stock #05-10117, quantity: (4). The process of battery replacement is described below: Remove the four feet screws and the bottom cover. -
