SECTION I UNPACKING & INSTALLATION
_______________________________________________________________
1-1. Introduction
The Model 4300B is a unique instrument capable of handling even the toughest resistance measurement
applications. The 4300B is designed to measure the low resistance of such items as coils, transformers,
ballasts, heater elements, etc. Some features of the 4300B that give it an edge over competitive products are:
"Charging Inductor" mode for reduced settling times.
"Disconnect Status" indicators designed with safety in mind.
Full 4-wire Kelvin terminal configuration.
Fully selectable test currents up to 10 amps.
Available locking rear Bendix connectors.
Available data outputs and remote programming capability.
Available high-speed version for assembly lines (4350ATE).
These features and more are discussed fully in the operating instructions of this manual.
This device may be
dangerous if used in a manner contrary to its design!
Please read this manual thoroughly before operating
your 4300B (4350ATE).
1-2. Initial
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
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.
1-3.
Line Voltage/Fuse Selection
The only adjustments required before placing the unit in operation are to set the rear panel switch to the
correct local AC line voltage and verify that the proper fuse for this voltage is installed as follows:
105 to 125 VAC = 3 Amp Slo-blo
210 to 250 VAC = 1 Amp Slo-blo
