The Tektronix DM501A is a 4½ digit True RMS multimeter plug-in for the TM500 system.
It replaced the DM501 (which suffered from accuracy limitations) in 1980. It also has a temperature input, requiring the P6601 PT-100 probe with a 2-pin LEMO S-series connector.
Key Specifications
DC Voltage ranges and accuracy | 200 mVDC to 200 VDC in decade ranges (0.05% + 0.01% (200 mV: 0.015%) FS), 1000 VDC (0.05% + 0.02% FS) |
---|---|
DC Voltage characteristics | Input resistance 10 MΩ, CMRR >100 dB at DC, 80 dB at 50 and 60 Hz (1 kΩ unbal.), NMRR 60 dB at 50 or 60 Hz |
AC Voltage ranges and accuracy | 200 mVDC to 200 VAC in decade ranges, and 500 VAC (0.6% + 0.05% (500 V:0.2%) FS, True RMS) |
AC Voltage characteristics | Input impedance 10 MΩ // ≤160 pF, CMRR 60 dB at 50 or 60 Hz (1 kΩ unbal.) |
DC Current ranges and accuracy | 200 μA to 2 A in decade ranges, 0.2% + 0.015% FS |
AC Current ranges and accuracy | 200 μA to 2 A in decade ranges, 0.6% + 0.05% FS (for 20 Hz to 10 kHz sine >5% FS) |
Ohms ranges and accuracy | 200 Ω to 20 MΩ in decade ranges, current 1 mA, 1 mA, 100 μA, ... 0.1 μA respectively; 0.15% (20 MΩ: 0.5%) + 0.015% FS |
Temperature range and accuracy | –62°C to +150°C (±2°C cal. probe, ±4°C uncal. probe), +150°C to +240°C (+0/-6°C or +2/-8°C any probe, uncal.) |
