Page 3: Safety Rules
SAFETY RULE WARNING This tester has been designed with your safety in mind. However, no design can completely protect against in- correct use. Electrical circuits can be dangerous and/ or lethal when lack of caution or poor safety practices are used. WARNING This meter is NOT to be used to measure High Energy circuits (power circuitry fused at greater than 4KW, such... - Page 4 l AC (310-C 1.800.561.8187 information@itm.com www. .com...
- Page 5 Make sure both test leads are fully inserted into their respec- tive input jacks (Black lead into COM and Red lead into ). A loose test lead may cause the user to misinter- pret the dangers present (the meter may read Zero when dangerous voltage is present) or the loose lead may accidentally short to other circuitry or shock the user.
- Page 6 Do not use the meter if it does not appear to work correctly on all ranges and in all modes. Do not use the meter if it has undergone long-term storage under unfavorable conditions. Do not use the meter if it may have been damaged in transport.
- Page 7 Do not mistake a downscale reading as an indication that no potential is present. Dangerous potentials may be present that may result in user injury. When replacing the battery, dispose of the depleted battery in accordance with any prevailing safety or environmental regulations.
- Page 8 DO NOT TOUCH Do not touch exposed wiring, connections or other “live” parts of an electrical circuit. If in doubt, check the circuit first for voltage before touching it. Turn off the power to a circuit before connecting test probes to it. Be sure there is no voltage present be- fore you touch the circuit.

Page 9: Introduction
INTRODUCTION The Triplett Model 310-TEL is a handy hand-sized VOM with all the versatility and performance of larger, more expensive bench-size models. It offers diode over- load protection against damage to the meter move- ment caused by accidental overloads. A fuse is used to protect the RX1 range. -

Page 12: General Instructions
GENERAL INSTRUCTIONS Control Locations For a diagram of the Model 310-TEL, please refer to page 14. Test Leads Check the test leads periodically. Leads that are worn, have damaged insulation, damaged plugs, damaged probes or loose parts should be replaced. The following section should be read carefully. -
Page 13: Scale Selection
Scale Selection Readings are taken on the scale having the appropri- ate significant figures (both 3 and 300 volts are read on the 0-300 scale) by multiplying or dividing by a factor of 10 or 100 as indicated by the range/scale ratio (i.e., on the 3 volt range, divide the scale read- ings by 100). -
Page 14: Other Considerations
Other Considerations Readings on the sensitive voltage, current and resis- tance ranges may sometimes be different than calcu- lated values. Thermo-electric or electro-chemical re- actions can sometimes generate voltage (and current) in a circuit due to elevated temperatures, contact of dissimilar metals, chemical fumes or moisture. -
