PEAK to PEAK VTVM
Information
Expressly designed for TV servicing, the model
232 (249)
Peak-to- Peak VTVM features a full-wave, high frequency
rectifier circuit that responds to and measures the
peak-to-peak voltage value of complex and sine waveforms
even when DC is present. It also reads the rms voltage of
sine waves (on a separate scale), dc voltage values, and
resistance values. For consistantly high accuracy, there are
seven non-skip ranges on all functions to provide a uniform
3 to 1 scale ratio between adjacent ranges.
The input resistance on all dc voltage ranges is 11 megohms,
which is high enough to prevent loading error and yet not so
high as to impair the stability of the instrument. The dc
voltage ranges may be extended to 30,000 volts (with
accessory High Voltage
Probe HVP“1 or HVP“2) and may also be
used for RFvoltage measurement up to250 me (with accessory
RF
Probe Model PRF~11). The frequency response of the ac
voltage ranges extends from 30cps to 3 me. for a source of
100 ohms or less.
Facilities that increase the accuracy, versatility, and ease
of operation include zero-center indication for
discriminator alignment and bias measurements; zero
adjustment unaffected by changing function or range;
separate scale for low ac voltage measurement; electronic
protection against meterburn out; adjustment of all
calibration controls without cabinet removal; and UNI-PROBE,
a single unit
Probe used for all functions.
The model
232 (4 1/2" meter) and the model
249 (7 1/2"
meter)are identical electrically. Where portability Is
desired, the model
232 is preferable because of its
extremely compact design. The model
249 is an ideal bench
instrument, having extra long scales to minimize reading
errors and permitting permanent placement of the equipment
at a practical working distance. Both instruments are
ruggedly housed, professional in appearance, and highly
dependable and trustworthy measuring devices that will prove
extremely valuable in television, fm-am radio servicing, and
many industrial applications.
