2500g is NOT 5.5oz.
2500g is about 5 POUNDS.
Something is WAY out of WHACK with those calibration instructions.

Yes, there is such a thing as NORMAL
, if you have to ask what is "NORMAL" , you probably aren't !

Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, and HAVOC !

GH,

It's most likely that my memory is out of whack.

Let me see. From "Calibrating the Scale."

"1. To Calibrate, or balance, Scale, press CAL for three seconds. Once the display shows "CAL", stop pressing button.

2. Press CAL button again. Place an item that weighs exactly 5.5 lb. (2500 G) on scale. Press CAL button again. The display will show "0". Keep the item on the platform.

3. Place another item weighing 5.5 lb. on platform. Press CAL again. The display will show "ACC", meaning the Scale is successfully calibrated."


Yep, it looks like I need to calibrate my memory. Hmm...

Good catch, GH!


Cheers,

WTH? I have to come up with two identical objects? What good are *you,* scale manufacturer?

(shrug, heavy sigh of resignation)

Sounds like bad Chinese English to me.

That, and the fact that the price is *one cent* below the "Free Shipping" amount.

That’s the one. I’ve had mine about 10 years, so the label looks a bit different. It’s perfect for rockets. The “TARE” button is great if you want to measure something where you want to zero out the weight of a container, like if you are measuring epoxy by pouring into a cup.

Add this to your order. You'll need it chasing rockets this summer.

I've been using an Adam Equipment CB1001 (up to 1kg in .1g increments) with good success.

I came across the following listing from a Big Box Store website, and I'm wondering if it will do.

For those of you who are experienced at this sort of thing, please respond accordingly. Thanks in advance!

"Insten

Silver New 200g x 0.01g Mini Digital Scale Jewelry Pocket Balance Gram LCD US

$7.97 List - WAS $19.99


Features

... lets you weigh gemstones and pieces of jewelry for precise valuation. It has a weight capacity of between 0.01 and 7.06 oz, which makes it sensitive enough for delicate work. This mini digital scale is small enough to fit in a purse or your pocket for easy transport. The unit powers down after 60 seconds without being used, which saves battery power. It automatically calibrates to save you time.

Suitable for precise weighing
Color: silver
Pocket size: 120 x 63 x 20 mm/ 4.72" x 2.48" x 0.79"
Capacity: 0.01 to 200 g/ 0.01 to 7.06 oz

I ordered what appears to be exactly the same scale as the one you posted...except this one reads up to 500 grams. Works great so far, no complaints.
