Installation / Setup
The Valhalla Scientific Model 4014 ohmmeter requires verification of the local AC line voltage and proper fuse installation before operation. For 105 to 125 VAC, use a 0.25 Amp Slo-Blo fuse; for 210 to 250 VAC, use a 0.125 Amp Slo-Blo fuse. If interfaces are installed, these values are doubled. Older models select voltage internally via jumpers, while newer models use a rear-panel sliding switch. The unit includes hardware for bench use, with no special instructions needed. For rack mounting, optional brackets are available, and the unit must be supported on both sides. Ensure ambient air temperature does not exceed 50°C during operation or 70°C when powered off. The power plug must be a three-contact device with a continuous ground connection.

Safety & Warnings
The power plug must be a three-contact device and should be inserted only into a three-contact mating socket where the third contact provides a ground connection. If power is provided through an extension cable, the ground connection must be continuous. Any discontinuity in the ground lead may render the unit unsafe for use!
