At the highest gain setting a 10µV RMS input signal at the correct frequency will give a full scale reading on the analogue front panel meter.\u003c\/p\u003e\n\u003cp\u003eThe 5918 electroding detector is completely self-contained in a portable carry case with shoulder strap. Integral rechargeable batteries are included and a separate mains power module is supplied to recharge them.\u003c\/p\u003e\n\u003cp\u003eIn use the 5918 detector is connected to the receiving probe, either a Tinsley type 5917 Beach probe or 5917D Divers Probe. The exact operating frequency is selected on the thumbwheel switches and the gain switch is adjusted to obtain a useful indication of the signal. A frequency of either 16.7Hz or 25Hz is recommended when using the 5917 Probes.\u003c\/p\u003e\n\u003cp\u003eAn audible output signal is available which can be heard by using the plug in headphones supplied. The larger the signal received the higher the frequency heard. A volume control is provided for adjustment of loudness.\u003c\/p\u003e\n\u003cp\u003eFor more information about this product \u003ca href=\"http:\/\/www.tinsley.co.uk\/contact\/index.html\"\u003econtact Tinsley\u003c\/a\u003e\u003c\/p\u003e","brand":"tinsley.co.uk","offers":[{"title":"Default Title","offer_id":57382861373775,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/2088\/5583\/files\/product-range_alt_5917.jpg?v=1775122099","url":"https:\/\/tinsley.co.uk\/products\/beach-probe-and-battery-powered-portable-electroding-detector-models-5917-and-5918","provider":"Tinsley Instrumentation Ltd","version":"1.0","type":"link"}
