The Я4С-97 is a digital multimeter plug-in for Soviet 7000-series clones. It is roughly analogous to the Tek 7D13.
Significant differences to the 7D13 include:
- 2 kV and 20 kV ranges using an external 100:1 probe
- mode and range switches are separate
- probe connector is a Soviet 8-pin rectangular type
- all modes except current need a special probe
Key Specifications
| Voltage ranges | 2 V, 20 V, 200 V, 2 kV, 20 kV |
|---|---|
| Current ranges | 2 mA, 20 mA, 200 mA, 2 A |
| Resistance ranges | 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ, 2 MΩ |
| Temperature range | -40 to 120 °C |
The internal architecture of the Я4С-97 seems to be very similar to the 7D13, even down to the 2 kHz clock and the transistor-based temperature sensor (which uses a transistor type 2T3316-1 as the probe). However, there is no DAC included for the readout, because the mainframe readout interface is digital, not analogue.
