Page 8: Chapter 1 - General Information
Essentially, a Model 4314KV/KVS is a 4-wire ohmmeter which has been designed to use very low test currents for its measurement. Additional circuitry proprietary to Valhalla Scientific is used to ensure that test current levels do not exceed the specified "failsafe current"... -
Page 9: Chapter 2 - Unpacking And Installing
Although the batteries are fully charged prior to shipment, it may be desirable to refresh the charge for 24 hours before use. As a rule of thumb, the 4314KV/KVS requires twice as much time to fully recharge as the amount of discharge time. For example, if the instrument was used continuously for 2 hours, the AC adapter must be connected for 4 hours in order to fully restore the charge. -

Option MP-2: Kelvin Mini-Probes Option "MP- 2" is a 48"shielded lead set, handheld pencil type, terminated in spring loaded steel tips with 0.18" separation. (1 Amp max.) Option MP-3: Kelvin Micro-Probes Option "MP-3" is a 48" shielded lead set (dual banana), handheld pencil type, terminated in spring loaded steel tips with .08"... -
Page 14: Chapter 5 - Features And Operations
Charging Jack The battery charging jack is a barrel type and is located on the 4314KV/KVS front panel. The center pin of the connector is positive. The charging requirements of the internal battery pack are 6VDC @ 1.25A. The correct charging voltage is supplied by the adapter included with the instrument. -

Page 17: Connections
In many applications the contact resistance can exceed the value of the load by several orders of magnitude. The 4314KV/KVS bypasses this potential error source by providing two terminals of constant current and an additional two terminals for high impedance voltage measurement. -
Page 18: Displays
If the display appears to be erroneous when connected to a load, recheck the test leads for integrity and cleanliness. If all external items appear to be functioning properly, the problem may be the ohmmeter. In this case, please contact your local Valhalla Scientific Sales Office. Current Display and Multiplier LEDs (KVS models only) Under normal operations, the Current display will indicate the value of the source current being used by the tester. -
Page 19: Fail-Safe Operation
The value measured is displayed on the Current window. If the Fail-Safe current measured ever exceeds the max values listed in Table 3, do not use the device and contact your local Valhalla Scientific Sales or Tech Support Office. -
Page 20: Low Battery Indicator
Low Battery Indicator A standard feature of 4314KV/KVS 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. • Non lit LED indicates that the batteries are charged and the device can be used. -
