Getting Started M703E Calibrator Operator’s Manual
3.4.2. WARM UP
The M703E Photometric calibrator requires a minimum of 30 minutes for all of its internal components to reach a
stable operating temperature. During that time, various portions of the instrument’s front panel will behave as
follows. See Figure 3-1 for locations.

calibration sequence.
Fault Red BLINKING
The calibrator is warming up and therefore many of its subsystems
are not yet operating within their optimum ranges. Various warning
messages will appear.
3.4.3. WARNING MESSAGES
Because internal temperatures and other conditions may be outside be specified limits during the calibrator’s
warm-up period, the software will suppress most warning conditions for 30 minutes after power up. If warning
messages persist after the 30 minutes warm up period is over, investigate their cause using the troubleshooting
guidelines in Chapter 11 of this manual.
