What statements are true about measurements and units?

Need more information right now I can tell you it is a weight measurement

Yes press and hold the units button for more than a second until the desired units show up

If you measure the height, width and depth you can calculate the volume. You multiple the height by depth by width. Make sure you use the same units for each measurement. For example if you want the volume in cubic feet, make sure all measurements are in feet. If the height is 5 feet 8 inches, you need to convert this to feet, which would be 5.67 feet, likewise for the other two measurements. It wont be exact because there will be bits sticking out but will be near enough. Make sure you also calculate the volume of the door space as that is included in the volume.

Check the fuses and battery contacts. Fuses that old can open without any current going thru them. If the battery contacts are corroded then clean them before installing a new battery

Procedure 6.4 - Troubleshooting the Generator
The generator performs three functions in the EFX. First, by controlling the amount of electrical
load applied to the generator, the user's pedalling resistance is controlled. Second, the generator
is used to charge the EFX's internal battery. Lastly, one of the generators six phase output
windings is monitored to determine when the unit is in use and when it is idle. This system also
determines the stride rate by determining the operating speed (output frequency) of the
monitored generator winding.
Warning
Because this is a self powered unit, it will either be necessary to either equip the unit with the
optional external power supply or have an assistant pedal on the unit while voltage
measurements are being taken. Because of the danger of working on the unit while it is in motion
using the optional external power supply is strongly recommended.
1. Perform the generator resistance test per Procedure 5.1. If any of the resistance
measurements are significantly high or significantly low, replace the generator.
2. The following voltage reading must be taken while the unit is in motion. Extreme care must
be taken to keep meter leads, hands, etc. clear of all moving parts. Using an AC voltmeter,
measure the voltage between 1 & 3, 2 & 3, 5 & 7 and 6 & 7 on J1 of the lower PCA. All AC
voltage readings will vary depending on the unit's stride rate at the time the measurement is
taken. At a stride rate of 100 strides per minute, all three voltage readings will be
approximately 100 VAC -110 VAC.
3. If any of the six readings in step 2 are significantly low, replace the generator.

1.They include some kind of self test
2.You can use the OSD to change display characteristics of the unit.

arif qc, Are you using a DMM that is or will make "true RMS" measurements or is it an "average responding" type of voltmeter? Is this APC ups designed for 120 vac input/output or is this unit a 220 vac input/output type? Use only a "TRUE RMS" type DMM to make your measurements!!! I believe if you visit Tripp-Lite site, you will find a tutorial video clip of why you should use a true-rms meter to make measurements of output voltages. 12fixlouie

your local dealer shouold have available to them all the manufacture specs and which unit would fit your needs.

You can use the units menu (2nd > 3) to place a unit after some number you want to qualify as being an unit, or you can just type them in like 5_ft + 6_in. Note that you need to add on each part if you are doing mixed measurements; there is no _ft_in combination. So just add each manually - in your case you would do (5_ft + 6_in) - (2_ft + 8_in)
