The Triple Display 194 is an innovative new concept in DMM design. The unique display enables you to view more than one event at a time. This eliminates the hassle of switching back and forth to review minimum, maximum or preset comparative values. The meter is also easy to use and built to last.
The DMM 194 is a hand-held autoranging DMM. The backlit LCD can display three readings at one time. In addition to basic function of AC/DC V, AC/DC A, Ohm, Diode test, continuity, Capacitance, Frequency, there is the adaptor function. The meter also has RS232 output and software for recording information into a PC.
The DMM 194 also features:
- REC: Records Min/Max readings during specified measurement intervals.
- COMP: Compare actual reading to preset HI and LOW value for Pass/Fail testing of component
- HOLD: Tow hold system automatically holds the previous stable reading when a new one is obtained.

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.
