The Simpson 260-8 is an analog multimeter with the provisions of measuring Voltage, Ohms and Milli-amperes. The manufacturer has named it a VOM. Each of the functions has a different scale and there is a mirror on the dial. Thus parallax is reduced and a better accuracy of the measurement is ensured.
Functions on the VOM
In fact, this instrument has the three major functions of voltage, current and resistance. DC voltage is measurable in nine ranges of 250mV, 1, 2.5, 10, 25, 50, 250, 500 and 1000V. AC voltage may be measured in 2.5, 10, 25, 50, 250, 500 and 1000V ranges. Accuracy varies between 2 and 3%. You can measure DC ampere in six ranges with the meter. The ranges available are 50µA, 1, 10, 100, 500mA and 10A. Well, there is no provision for AC ampere here.
Resistance measurement with the meter is possible in three ranges. The ranges are R X 1, R X 100 and R X 10K. Most interesting thing is, you can measure audible signal on the instrument in decibels.
Well designed different scales are there on the dial of the instrument that helps read any measurement accurately. Parallax is minimized by the mirror on the dial. There are two knobs to select function and range. Another knob to adjust zero on resistance measurement is also there on the meter.
- Operation is simple
- Tri colored marking of dial makes it easy to read
- Jacks are safe as reverse is recessed
- Strong outer casing for longer lasting
- Portable and workable both in field and work shop
- Test leads are long and probes are threaded for extension
In the digitally flourishing present time, an analog instrument is surprising. Still, its simplicity and ruggedness may be interesting to some users.
