- 2000 Series Enhanced Features
Auto-polarity on all DC functions with red NEG indicator. Ohmmeter Voltage Mode detects foreign voltage of either polarity. Multi-turn Ohmmeter Adjust for more accurate setting of Ohmmeter zero. Power saving sleep feature prevents draining of the batteries if accidentally left on. Dry contact requires no adjustment to measure relay contact on time. Measures rate directly without counting pointer swings. Can detect and hold 2 msec momentary closures. Selectable DC Amps Polarity (Auto, Positive, Negative). Will measure pulse code transmit and receive currents independently.
- Direct Measurement of Code Parameters
Directly measures code parameters in any AC or DC range. No counting of pointer swings or adjustments are necessary. Peak Follow allows downward adjustment of peak levels.
- Accurately measures code parameters to 420 cpm.
- CAB Filter Options (2001,2002, & 2003)
Allow measurements of all code parameters for selected cab frequencies without shutting down equipment. Active in all AC Volts and AC Amps Ranges.
- Safety Features
Shrouded safety jacks and spring-loaded shroud on test lead plugs. Fused on all ranges and functions except 6A and 30A. Battery/Lamp Test and Battery Monitor prevent false readings from weak batteries.
- Mechanical Features
Rugged, lightweight, weather-resistant case. Secondary protective window (field replaceable). Modular construction for easier repair and upgrade. One Year Warranty on construction and calibration.
