The 126 is a hand-held autoranging DMM. The 126 measures ACV, DCV, ACA, DCA, Resistance, Diodes and Continuity. The DMM 126 also features:

  • REC: Records Min/Max readings during specified measurement intervals.
  • AC/DC: Toggles between AC/DC volts and Amps.
  • RANGE: Allows the user to manually range the 126 instead of autoranging.
  • Data Hold: Holds the reading on the display for easy viewing.
  • Auto Off: Preserves battery life.

Additional Features and Benefits of the Model 126:

  • Agency Approval: Meets CE and IEC 1010 requirements.
  • Record: Records Min/Max values.
  • Range: Allows you to either manual range or use auto range to select the appropriate range.
  • Auto Off: Preserves battery life. LCD shows oFF when in this mode. Automatically powers down after 30 minutes of inactivity.

The 126 comes complete with the following accessories:

  • 126 Instrument
  • Rubber Boot
  • Fuse, 0.5 Amp
  • Test Lead Set
  • Instruction Manual
  • 2 each 1.5 volt AA Batteries

Category Ratings:

  • Category I: Usually electronic equipment or equipment where measures have been taken to limit transient over voltages.
  • Category II: Single phase loads like appliance personal computers, television sets, and other household loads. Outlets located more than 30 feet froma CAT III source or more than 60 feet from a CAT IV source.
  • Category III: Distribution level fixed installations like distribution panel devices, short branch and feeder circuits, three phase loads, and single phase commercial lighting.
  • Category IV: Equipment and lines located on the power line side of a service panel or where a low voltage connection is made to utility power

Frequently Asked Questions

1. Is there a way to measure higher current with a TPI DMM?

TPI DMMs (except the 120 and 126) have the capacity to read up to 10A AC/DC. Optional adapters are available for all models to increase the current range. Our shunt adapters are available to increase the range up to 1,000A AC/DC.

2. What other adapters are available for TPI DMMs?

Various adapters including carbon monoxide (A771), pressure (A620/630), and clamp-on low current (A254) are available. Contact TPI for additional information.

3. Which of the TPI DMMs will measure temperature?

All TPI DMMs can measure temperature by using the optional A301 K-Type thermocouple temperature adapter.

4. Which TPI DMMs can measure DC millivolts?

All TPI DMMs measure millivolts. Models are available with 1 or 0.1 millivolt resolution.

5. Which TPI DMMs can measure DC microamps?

The TPI 126, 133, 135, 153, 163, 183, 190, 194, 196, and 440 all have this capability.

6. Which TPI DMMs will measure capacitance?

The TPI 135, 183, 190, 192, 194, and 440 all have this capability.

7. What is continuity?

Continuity refers to a test performed on wires and circuits to see if a break(open) exhists. If the wire or circuit is continuous, the resistance reading will be at or near zero. The continuity range on a meter provides audible indication of a continuous circuit, allowing quicker tests without having to take your eyes off the circuit or wire under test.
