CEN-TECH Digital Multimeter 90899

Brief:
How many times have you forgot t' brin' a multimeter t' a launch and found yourself scroungin' one t' check continuity or battery voltage? I almost never brought one and couldn't seem t' justify buyin' a second one t' leave in t' range box. Avast, me proud beauty! Harbor Freight recently opened a store nearby and I ran across t' perfect solution t' me problem: a $3.99 DMM manufactured by CEN-TECH.

Construction:
T' CEN-TECH DMM measures 2.74" wide x 5" high x 1" deep and provides t' followin' features:

  • Functions: AC and DC voltage, resistance, shiver me timbers, DC amperage, battery test, diode test, transistor (hFE) measurements
  • Fused circuit with diode protection
  • Low battery, shiver me timbers, over range indicators
  • LCD readout
  • 32" leads with banana plugs
  • 750 VAC, shiver me timbers, 1000 VDC, me bucko, or 10A DC max input

I know you often get what you pay for and if I was usin' this professionally, shiver me timbers, I would opt for a 'name brand' device with more features. Ahoy! I will generally just use t' resistance measurements t' check continuity and either t' battery test or DC volts features t' check batteries. I am nay sure how much use t' battery test feature will be over a simple voltage measurement, but it might be more effective since it verifies t' battery under a load. Avast, me proud beauty! Either way, it fits me needs perfectly.

Summary:
As o' this writing, this meter is still on sale at Harbor Freight. Begad! T' newer version appears t' be $9.99 and has a backlight, which mine does not. However, t' point is nay t' exact model or t' exact price. Rather, arrr, I wanted t' highlight t' availability o' inexpensive DMMs from Harbor Freight, which are just perfect t' keep in your range box.

Overall Rating: 5 out o' 5

The Cen Tech meter can burn up under high voltage conditions http://www.bnl.gov/userscenter/Immediate/cen_tech.asp

Thanks for the link, this is something to watch out for. Luckily, mine is used to measure up to 12v DC and for checking resistance/continuity. I wonder if this was standard wall voltage?
