The MTD32 is designed to measure instantaneous current values over 32 channels.
MTD32 mezzanine performs measurements in the following modes:
- “Once” - a single measurement of the sequence of channels specified by the user is performed;
- “Block” - measurements are performed until a predetermined number of samples (results) of channel sequences specified by the user are received;
- “Continuous” - measurements are performed according to a user-defined sequence in a continuous cycle until a stop command is received.
|Number of measuring channels 32||
Measurement ranges of instantaneous current values:
Limits of permissible basic relative measurement error of instantaneous current values at the minimum sampling period and at ambient temperature + (20 ± 2) °С,%:
||Limits of permissible additional relative measurement error of instantaneous current values with a minimum sampling period,% ± 0.002 × T, where T is the deviation of the ambient temperature from 18 ºС (for the temperature range from 5 to 18 ºС) or from 22 ºС (for the interval temperatures from 22 to 40 ºС)|
|The maximum permissible current value on the mezzanine measuring shunts is not more than 30 mA||The period for obtaining the measurement results is set the same for all channels participating in the measurements, in the range from 302 μs to 16.777214 in increments of 1 μs|
|Measuring shunt resistance 240.0 ± 0.1 Ohm||The mezzanine measuring chains are galvanically isolated from the housing. Galvanic isolation voltage of at least 150 V. Resistance of galvanic isolation of at least 20 MOhm|
