| Basic specifications |
|
| Measurement functions |
Number of channels: 1, voltage measurement/current measurement using a clamp |
| Input |
Metal BNC connector, Max. rated voltage to earth: 30 V RMS or 60 V DC (with input isolated from the unit, the maximum voltage that can be applied between input channels andchassis, or across input pins, without causing damage, ±12 V common ground for installed units when using a clamp)
Sensor connector: CLAMP SENSOR 9270s input (±12 V common ground for installed units) |
| Voltage measurement range |
1 mV to 5 V/division, 12 ranges, full-scale = 20 divisions, AC voltage for possible measurement / display using the memory function: 30 V rms, low-pass filter: 5/500/100 k/1 MHz |
| Current measurement range |
With the 9270, 9272-10 (20 A), 9277, 3273, 3273-50 or 3276: 10 mA to 5 A/division, 9 ranges, full-scale = 20 divisions
With the 9271, 9272-10 (200 A), 9278, or 3274: 100 mA to 50 A/division, 9 ranges, full-scale = 20 divisions
With the 9279: 200 mA to 100 A/division, 9 ranges, full-scale = 20 divisions
With the 3275: 100 mA to 100 A/division, 10 ranges, full-scale = 20 divisions
Low-pass filter: 5/500/100 k/1 MHz
(1 MHz: 3273/3274/3275, 100 kHz: When using the 3273, 3274, 3275, 9277, or 9278) |
| Measurement resolution |

| Input resistance and capacitance |
1 M-ohm, 50 pF (when C is 100 kHz) |
| Input coupling |
DC, GND, AC |
| Max. allowable input |
30 V rms or 60 V DC (the maximum voltage that can be applied between input pins without causing damage) |
| Power terminal |
±12 V for the 3273/3273-50/3274/3275
(common ground with the power terminals of installed units) |
