The rated temperature limits for the local meter are listed above and are
true in that no damage to the meter will occur over these temperatures,
however the readability of the LCD is affected if taken to these
temperature extremes:
• The LCD will turn black at some temperature between 80 to 90 °C
(176 and 194 °F), rendering the display unreadable. This effect is
only temporary, and normally occurs at 90 °C (194 °F).
• At low temperatures, the update rate of the display is lengthened to
1.5 seconds due to the slower response time of the display. At -20
°C (-4 °F) the display becomes unreadable due to slow response of
the LCD. This is also only temporary and normal readability will
return when temperature returns above -20 °C (-4 °F).
