Will tread depth of tires affect accuracy of nitestar dmi?

it will be absolute minimal and would be within the accuracy of the unit
as tread depth is around 3/8" on new tyres and is around 1/8 (legal) on worn tyres as you can see the difference is hardly worth mentioning
if the unit is measuring distance travelled then the shallower the tread depth the greater the chance of tyre slip when driving and that will affect accuracy

Have a CVS blood pressure unit BP3MU1-1E. The cuff is too large for my 95 yr. old mother. How do I get a smaller cuff? The stores have none!!

Switch to the leg. You can take the pressure on the calf or the thigh. The thigh is easier. Place the cuff closer to the knee and if the sensor can be seen on the units cuff put that under the leg close to the knee joint. Inflate as normal. The reading may be higher than you expect by 10% So if it says 140/80 it would be 126/72

How to test monitor for accuracy

Best thing is to take it to your doctor and compare his readings, under the same conditions, as BP varies a lot in one person.

My 1992 Jeep wrangler has a hissing noise coming from the back of the steering column and is having trouble shifting

Normally a hissing noise when the engine is running is a vac leak.
I'm not aware of anything behind the speedo that would be affected but you might check for vac hoses. Might be the power brake booster leaking vac but that is in the engine compartment.

Can you calibrate omron hem-711

I check the accuracy of my Omron every year. It is important that your device must give proper results.

My Omron 711 seems to register readings that are too high when compared to doctor's office or monitors in drug stores, etc. Is there a way to check accuracy of the monitor?

Take the cuff to your doctors office and have the nurse check with yours and the office BP cuff. If your cuff is too small, you will get a false high reading.

Can you calibrate omron hem-711?

Depends what you mean by calibrate. If you mean affect adjustment - no, this is not possible. If you mean test the device for accuracy, then the answer is yes. All good quality home use Blood Pressure Monitors (BPM), should meet international standards, typically this is an accuracy of +/- 3 mmHg. To have a BPM checked for accuracy you should take it to an authorised reseller. Typically this should be done every two years.

Hiss in new fender frontman 65R. Can't seem to dial it out in either input.

A certain amount of "hiss" is present in electronic amps due to the statistical noise in electronics.

The hiss should be WELL below the level you get when playing. If you put you ear to the speaker, expect to hear some hiss with nothing plugged in. Ten feet away it should be very faint.

Accuracy problem

Hello martintpjr, the difference could be your physical postion,(sitting,laying) location of cuff(on the fore arm), not as relaxed, cuff/tubing has a air leak,or unit is out of calibration. Eliminate the first four than contact the local college or BioMed shop in the local hospital and KINDLY ask if your unit operation/calibration could be checked. Merry Christmas.
