Possible different model number, and discussion of similar models since neither manual appears to be online. Craftsman 73756 is similar but not exactly the same, and no manual found online.

Craftsman Clamp meter 034-90273 - no manual found online at Sears or elsewhere in searches.

Possible similar model with a free manual:

Suggest calling Sears as online search doesn't list it.

SOURCE: How do you check voltage utilizing the Craftsman

If you don't have to drive, set the multimeter to 20 V DC, and measure on the battery poles. If you'd like to drive during measurement, you could measure on the cigar lighter socket.

SOURCE: need owners manual for a

type this into your web browser owners manual for a Jensen JTM97, digital multimeter and you should be able to get what you need.

SOURCE: i have 800va microtek inverter non sine wave.i want to know what is the output voltage available

The voltage should be the same for both. Maybe one or the other isn't calibrated correctly. Have a friend with another multimeter check the output, and then take the voltage that is the same from his and yours.

meter needs to be serviced

clean terminals with cotton bud and ISO and then blow with air

dirty terminals may trigger 'leads' error

That is normal because:

Vrms[full-wave]=Vm/sqr2

Vrm[half-wave]=Vm/2

Vrms[full-wave]=Vm/sqr2

Vrm[half-wave]=Vm/2

Try cleaning terminals ( dirt inside triggers leads message).

use cottons bud and some Iso.

maybe this manual helps since you did not say what the problem is with your unit

short inside somewhere - check it out or buy new meter

I dont think This particular model is a True Rms Type . So you will not get accurate reading as of a True RMS Multimeter in AC . But in DC you Should atlest get an accuracy of 0.015

Please Rate My answer well and Support me !!!

The rms voltage is what counts, because it tells how much power the output will deliver to a resistive load. Inexpensive multimeters on their AC ranges are usually average-responding rms-calibrated meters. This means they measure the average of the absolute value of the AC component of the signal, and display that average multiplied by about 1.11 (actually, pi over sqrt(8)), the ratio of rms to average value for a pure sine wave. That way, the meter will give the right rms reading for a sine wave.

If the signal is a square wave, where the average and rms values are equal, the average-responding meter will read 11% too high.

Many inverters put out a modified sine wave (MSW), which sits at zero for a while, goes to a constant positive level for a while, goes back to zero for a while, and goes to a constant negative level for a while to complete the cycle. The positive and negative parts of the signal have the same magnitude and duration.

The rms and average values of an MSW depend on its duty cycle D, the fraction of a cycle for which the signal is not at zero. In a well-designed inverter, the duty cycle will be adjusted when the DC input voltage goes up and down to maintain the nominal rms output voltage. If we use peak voltage Vp to mean the magnitude of the positive and negative voltages the signal goes to, then Vavg for an MSW is equal to Vp times D, and Vrms is equal to Vp times the square root of D.

The duty cycle for which an MSW will have the same rms to average ratio as a sine wave is 8 over pi squared, or 81%. For any duty cycle less than this, an average-responding meter will read a lower voltage than the inverter rms output, and for a duty cycle higher than this, the meter will read too high.

If your MSW inverter is putting out 120 volts rms and its duty cycle varies from 50% to 75%, the meter reading will vary from 94 volts to 115 volts. I avoid the problem by using a Radio Shack 22-174B true rms digital multimeter.

If the signal is a square wave, where the average and rms values are equal, the average-responding meter will read 11% too high.
