Response Time: ranges from 5 seconds in the lowest range to under 2 seconds
in highest range when measuring from 10% to 90% of final value
Measurement Readouts: simultaneous display of rate and either the integrated
reading, highest rate (peak hold), or pulsed mode status
LCD Display: 8.9 cm (3.5 in.) diagonal, 240 H x 320 W pixels, TFT active matrix,
262K colors, 220 cd/m², backlighting automatically controlled by built-in light

°C (32 to 104 °F) shall be within 15% of the mean response determined at room
temperature, and the mean response from -10 to 0 °C (14 to 32 °F) shall be
within 20% of the mean response at room temperature.
