NOTICE
Power supply
‣
The TMT162 must be powered by a 11 to 40 V DC power supply with a limited power
according to NEC Class 02 (low voltage, low current) limited to 8 A and 150 VA in case
of a short circuit (according to IEC 61010-1 (EN 61010-1, CSA 1010.1-92).

Reference operating
conditions
Calibration temperature: 77 °F ± 9°F (+25 °C ± 5 °C)
Maximum measured error
The accuracy data are typical values and correspond to a standard deviation of ± 3 (normal
distribution), i.e. 99.8% of all the measured values achieve the given values or better values.
