    Description

    Simpson 311 Series assembled AC/DC/Ohms test probe set
    The Simpson 311 series probe is very specific requiring a unique lead configuration
    Note: this meter came in several versions and can have 1 of 2 different probe connectors
    The original 311 uses the Large Connector
    The larger connector is 5/8" in diameter and is a Switchcraft 2501
    The 311-3 uses the Small Connector
    The smaller connector is a 7/16" connector and is a "Rare" semi custom connector (this is the connector in the photo of the assembled test lead)
    please measure your probe connection and send me a message when you place your order - I will automatically supply the larger connector if no message is received.
    This meter uses 2 seperate Probes, which are connected to one Microphone connector and a separate Ground Lead:
    DC Probe - New Old Stock Microphone Connector - RG174 Coax Cable to a Black Test Probe with Custom 7 Meg ohm Resistor network.
    AC/Ohms Probe - Probe can be supplied with either a Switchcraft 2501 or New Old Stock Microphone Connector depending on meter
    RG174 Coax Cable to a Red Test Probe  (Labeled "AC/Ohms")
    Ground Wire  - Black Banana Plug - Black Test Lead Wire to Alligator Clip
    A word about the "Vintage Microphone Connector" - The microphone connectors used on these meter probes is a New Old Stock microphone Connector which has been out of production for roughly 40 years and so far I cannot find an accurate description for this style of connector - on the exterior it is identical to a Calrad MC150 connector but the threads are slightly different and Genuine NOS Calrad Connectors do not mate to the meter - The connector appears to be a generic version of an Amphenol 80-75MC1 but these too are so old I can find no specifications however, I can confirm that these connectors work on the Simpson Meter and match some of the Old Connectors I received with my 303 meter - due to rarity and age the supply of these connectors is growing exceedingly thin with most laying around in dusty store rooms and warehouses somewhere with no one knowing what they are!
    The calrad/amphenol style connector is the 2nd from the right in the supplied comparison photo
    (Left to Right - BNC, Switchcraft 2501F, Vintage Microphone Connector, Switchcraft 5501F)
    The unit is presented in a Labeled, Retail Quality, Reusable, 4 Mil Poly Ziplock Bag and is wrapped with a Reusable Velcro Strip to keep the leads organized and ready.
    This is hand assembled of the following components:
    1 Pair of Genuine Philmore Test Lead Probes - 1 Red/1 Black
    1 Microphone Connector Either Switchcraft (also known as Amphenol "Mini" Mic Connector)
    7 Meg Ohms of Resistance
    1 Alligator Clip & Heat Shrink Tubing
    2 Laminated Self Adhesive Probe Labels and Clear Heat Shrink Tubing to cover the probe labels, resulting in a professional and durable setup (see photos)
    2 36" length of RG174 Coaxial Wire for DC Lead (Very Flexible - makes a great test lead)
    1 36" Length of 18 Gauge Black Rubber Test Lead Wire (PowerWerx brand Very Flexible - High Quality) for the Ground Lead
    I have shipped these probes and kits to several dozen countries and have received nothing but praise for bot the kits and probes, I think you too will be pleased with this simple and durable set to get that old meter back in service!
