1503C MTDR User Manual
When operating the 1503C in an environment below +10
°
C, a heater will activate.
The element is built into the LCD module and will heat the display to permit normal
operation. Depending on the surrounding temperature, it might take up to 15
minutes to completely warm the crystals in the LCD. Once warmed, the display will
operate normally.
Preparing to Use the 1503C
Check the power requirements, remove the front cover, and you are ready to test
cables. The following pages explain the front-panel controls.
