Looking Back at Yesteryear's Measurement Tools - EE Times

Peter turned the device over to his colleague Andrew Bruno, who put it on a test rig to find out that it still functioned (Fig 4a + 4b). A simple design can lead to a long operational lifetime, but being built ruggedly enough to be used as a... I built a 6/12 V tester using heating elements from several waffle irons bought from a thrift store and connected using welding cables. But it was a good way to convince people to buy a new battery from me. . A bit more honest than squirting oil on shock absorbers. That rugged durability demanded of field tools created a fusion of practicality and simple beauty that is hard to match today, if only because the amount of attention needed would price a current tool out of the marketplace. Didn't often use it on 'good' batteries. SO you could get at the individual 2V cells with just such a tester as shown, and measure them individually. {* #registrationForm *} {* emailAddress *} {* newPassword *} {* newPasswordConfirm *} {* displayName *} {* firstName *} {* lastName *} {* addressCountry *} {* companyName *} {* eetimesJobfunction *} {* jobFunctionOther *} {* eetimesIndustry *} {*... It included an induction ammeter and connections for my voltmeter - worked OK for short term tests as the elements got very hot on a healthy 12 V battery. Most don't have the same 'devil's fork' shape anymore as terminal configurations are varied but the principal is the same - drop a big load across a charged battery and see what output current it can sustain. The second device was certainly some kind of tester, but I couldn’t place it to save my life (Fig 3). Quite formidable looking, the tool had two massive prongs issuing from a stout wooden handle, almost weapons-like in appearance. You can't say much about a lead/acid battery unless you can test it under high discharge conditions as the internal resistance is not measurable w/o dropping a big load across it. ss/wb. A friend of mine bought a 12V version recently off EBay - same thing - a hefty resistor with a voltmeter across it. Has to be 12V these days because the interconnections are inside the battery. One of the devices in my collection, a Weston Model 1000 from the 1930’s (Fig 5) also screams rugged practicality, with the same big gauge and knob that begs you to turn it that a good field test device should have, even today. Yet that old-school meticulous craftsmanship comes through in the hand-loomed layout and individually-wound resistors inside it (if you zoom in on Figure 6 you can see where someone repaired it with a resistor modern to the device but antique to... This intimidating aura was reinforced by the “100A” and “200A” markings on the side (visible if you zoom in), on a bus bar that one’s thumb could easily touch while using it. The incredibly high amperage in the resistors set into the handle was... Initially I had only identified the old circuit tester, as it has a face easily recognized by anyone who has worked with such tools (Fig 2). It’s friendly face with bold gauge and grippy selector knob shouted precision and practicality, reinforced... In the good old days (from whence I come) car batteries had the individual 2V cells externally connected to form a 6V or 12V battery. We rapidly found out that it is an old-timey battery tester, as old batteries used to be very low voltage, but deliver a very high current. I used to use one of these battery testers on 6V/12V automotive batteries in the late '60s-early '70s. Similar units are still used in auto repair shops worldwide. Source:

Verizon refutes claims about Fios battery backup process - FierceTelecom

” Marcus said that the Fios installer told him to turn off the switch on the power unit because leaving it on when power was operating would drain the dry cell batteries. Although consumers could leave the switch on, Verizon offers no estimate of what the battery life time is when the battery is left on. This is unlike the automatic switchover that the earlier generation, shorter-battery-life unit had. Source:
