Battery Life

WWarning

To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator (B) appears.

Table 12 shows typical alkaline battery life. To preserve battery life:

∙Use current simulation instead of sourcing when possible.

∙Avoid using the backlight.

∙Do not disable the automatic power-off feature.

∙Turn the meter off when you are not using it.

Using the Holster and Flex-Stand

The meter is supplied with a snap-on holster that absorbs shocks and protects the meter from rough handling. You can turn the meter over in the holster to protect the face of the meter from scratches when carrying the meter.

The holster is equipped with a Flex-Stand bail. Some uses of the holster with Flex-Stand are shown in Figure 9.
