Division (d) Measurement procedure
United Kingdom
To measure time, an ordinary stopwatch and timing to a resolution of one second is sufficient. All power figures are to be recorded in watts (W). Table 9 outlines the steps of the OM test procedure.
Service/maintenance modes (including colour calibration) generally should not be included in measurements. Any adaptation of the procedure needed to exclude such modes that occur during the test must be noted.
As stated above, all power measurements are to be made in accordance with IEC 62301. Depending on the nature of the mode, IEC 62301 provides for instantaneous power measurements, five-minute accumulated energy measurements, or accumulated energy measurements over periods long enough to properly assess cyclical consumption patterns. Regardless of the method, only power values should be reported.

OM test procedure
| Notes: | |||
| — Before beginning the test, it is helpful to check the power-management default delay times to ensure they are as shipped. | |||
| — Step 1 — If the unit has no ready indicator, use the time at which the power consumption level stabilises to the ready level, and note this detail when reporting the product test data. | |||
| — Steps 4 and 5 — For products with more than one sleep level, repeat these steps as many times as necessary to capture all successive sleep levels and report these data. Two sleep levels are typically used in large-format copiers and MFDs that use high-heat marking technologies. For products lacking this mode, disregard steps 4 and 5. | |||
| — Steps 4 and 6 — Default delay time measurements are to be made in parallel, cumulative from the start of step 4. For example, a product set to enter a sleep level in 15 minutes and enter a second sleep level 30 minutes after entering the first sleep level will have a 15-minute default delay time to the first level and a 45-minute default delay time to the second level. | |||
| — Steps 6 and 7 — Most OM products do not have a distinct auto-off mode. For products lacking this mode, disregard steps 6 and 7. | |||
| — Step 8 — If the unit has no power switch, wait until it enters its lowest power mode and note this detail when reporting the product test data. | |||
| Step | Initial state | Action | Record |
|---|---|---|---|
| 1 | Off | Plug the unit into meter. Turn on unit. Wait until unit indicates it is in ready mode. | — |
| 2 | Ready | Print, copy, or scan a single image. | — |
| 3 | Ready | Measure ready power. | Ready power |
| 4 | Ready | Wait default delay time to sleep. | Sleep default delay time |
| 5 | Sleep | Measure sleep power. | Sleep power |
| 6 | Sleep | Wait default delay time to auto-off. | Auto-off default delay time |
| 7 | Auto-off | Measure auto-off power. | Auto-off power |
| 8 | Off | Manually turn device off. Wait until unit is off. | — |
| 9 | Off | Measure off power. | Off power |
