    Instrument a general purpose, portable or laboratory Instrument. It is well suited to servicing, production, inspection and engineering applications. The 260 uses the Simpson taut-band movement, which is self-shielding. The taut- band suspension provides a high degree of repeatability and is highly resistant to shock or vibration.

  • Page 8: Accessories And Supplies

    All accessories and supplies required for the operation of the 260 is furnished with each instrument, and listed in Table 1-2. Technical Data Table 1-1 lists the technical specifications for the Simpson 260-6XLPM Volt-Ohm- Milliammeter. NOTE: Accuracy specifications apply to measurements made with the Instrument in a horizontal position (meter facing upward).

    A pair of test leads, one black and one red, are also included. Warranty The Simpson Electric Company warranty policy is located on the inside front cover of this manual. Read it carefully before requesting a warranty repair. For all assis- tance, including help with the Instrument under warranty, contact the nearest Au- thorized Service Center for instructions.

  • Page 12: Controls, Connectors & Indicators

    It is recommended that the Instrument be returned annually to your nearest Simpson Authorized Service Center, or to the factory, for an overall check, adjustment and calibration. When not in use, store the Instrument in a room free from temperature ex- tremes, dust, corrosive fumes and mechanical vibration or shock.

  • Page 13: Operation

    Table 3-1. Controls and Connectors Range Switch: The range switch has 18 positions. It may be turned to any position from either direction. There are seven voltage po- sitions, four direct current, six resistance and an OFF/TRAN- SIT position. Two of the resistance positions are for Low Power Ohms.

  • Page 14: Safety Precautions

    Safety Precautions The 260 is intended for use only by personnel qualified to recognize shock haz- ards and trained in the safety precautions required to avoid possible injury. Do not work alone when making measurements of circuits where a shock hazard might exist.

    screw located in the meter cover below the center of the dial. Use a small screw- driver to turn the screw slowly clockwise or counterclockwise until the pointer rests freely over the zero mark at the left end of the scale. This procedure will avoid disturbances to the zero setting by subsequent changes in temperature, humidity, vibration and other environmental conditions.

  • Page 16: Measuring Dc Voltage: 0-1000V

    4.7.1 Measuring AC Voltage NOTE: The Simpson 260-6XLPM responds to the full wave average value of an AC waveform. It is calibrated in terms of the RMS value of a pure sine wave. If the waveform is nonsinusoidal, the reading might be either higher or lower than the true RMS value and could result in a substantial error.

Typical Frequency Response, ACV Ranges Set the function switch to AC. Set the range switch to one of the six voltage range positions marked 2.5V, 10V, 25V, 100V, 250V or 500V.

  • Page 18: Output Voltage Measurements

    Be sure the power is off in the circuit being measured and that all its capaci- tors have been discharged. Connect the test leads to the circuit with the black lead on the ground side. Turn on the power in the circuit being measured. Read the voltage on the red scale marked AC.

  • Page 19: Measuring Decibels

    Measuring Decibels To read voltages in terms of decibels, use the decibel (dB) scale on the bottom of the dial marked from -20 to +10. Read the dB scale by first following the instruc- tions for measuring AC. When the range switch is set on the 2.5V position, read the dB scale directly.

  • Page 20: Measuring Direct Current: 0-5A

    Read the current in mA on the black DC scale marked 0-50 for the 0.5 mA ranges, divide the reading by 100 and 10, respectively. Read the 50 mA range directly. Multiply the reading on the 500 mA range by 10. Turn power off, disconnect test leads and return the range switch to the OFF/ TRANSIT position.

  • Page 21: Measuring Resistance: Conventional Ohm Ranges

    NOTE: When the Instrument is not in use, do not leave the range switch in the low power ohms position because power is drawn continuously from the 1.5V battery. 4.11.2 Measuring Resistance: Conventional Ohm Ranges Turn the range switch to the desired range and the function switch to either the +DC or -DC position.
