SECTION I UNPACKING & INSTALLATION
_______________________________________________________________
1-1. Introduction
The Vitrek 4600A is a Precision High Voltage Measurement Instrument. It is the ideal instrument for
calibrating Hipot testers and measuring and calibrating a wide variety of high voltage power sources.
The 4600A features a 4½-digit (19999 count) display, two voltage ranges (2kV and 20kV) and either
DC or true RMS AC measurement modes. The 4600A operates from 115/230 VAC 50-60 Hz line
power. An internal rechargeable battery supply is optionally available (typical battery life is 5-6 hours
between charges).
The 4600A has been designed with safety in mind. However, high voltages may be hazardous or
fatal if mis-handled! Please read this manual thoroughly, and follow all safety precautions in section 1-
7, before attempting to operate the Model 4600A.
1-2. Inspection
If the shipping carton is damaged, request that the carrier's agent be present when the unit is unpacked.
If the instrument appears damaged, the carrier's agent should authorize repairs before the unit is returned
to the factory. Even if the instrument appears undamaged, it may have suffered internal damage in
transit that may not be evident until the unit is operated or tested to verify conformance with its
specifications. If the unit fails to operate or fails to meet the performance specifications of Section 2,
notify the carrier's agent and the nearest Vitrek Sales Office. Retain the shipping carton for the carrier's
inspection. DO NOT return equipment to Vitrek Corporation or any of its sales offices prior to
obtaining authorization to do so.
1-3. Fuse Protection
The Model 4600A uses two internal fuses, one to protect the main power supply from an over current
condition and other protects the battery option from receiving an excessive charging current. Both fuses
are the same type: 5 X 20mm, 250VAC, 1A slow-blo fuse. If either fuse is blown, it may indicate a
problem with the internal power supply circuits. Refer all servicing of this instrument to qualified
technical personnel. For protection against fire, Replace fuses with the exact equivalent only!
1-4. Bench Use
The unit is supplied with all the hardware required for bench use and special instructions for use in this
manner are not necessary. The user should become familiar with the operating instructions in Section 4
before attempting to operate the voltmeter.
