Vintage Simpson Model 260 Series 4 Multimeter

• Multimeter is not in good working order, meter deflection doesn't go beyond midscale.
• Includes manufacture circuit diagram, operators manual, calibration, and alignment procedures.
• With batteries installed and on thes 50 v scale, measuring a 9v dc battery, reads close to correct value however, on the 10 v scale meter deflection stops at midscale. 
• Resistance function not tested, but deflection stops at midscale.
• I personally used a VOM similar to this one when I performed maintenance on the F4 fighter jets at HAFB in the1960's.
• Multimeter possibly may be repaired, or just used for parts. 
• Includes meter leads, batteries, and manuals.
• We combine shipping.
