Press the HZ/% button again to return to regular voltage or current measurement.

b) Range Button (fig. p.2 #3)

When the meter is switched on, it automatically goes into auto ranging ("AUTO" indication on the display). This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. For measurements situations requiring a manually selected range, perform the following steps:

1. Press the RANGE button; the "AUTO" indication on the display will disappear.
2. Press the RANGE button repeatedly to skip through the available ranges until the required one is selected.
3. To return to auto ranging, press and hold the RANGE button for more than 2 seconds.

c) Relative Button (fig. p.2 #4)

The relative measurement feature allows you to make measurements relative to a stored reference value. A reference voltage, current etc. can be stored and measurements made in comparison to that value. The displayed value is the difference between the reference value and the measured value.

1. Perform any measurement as described in the operating instructions.

7. Ma intenance

CAUTION: Before opening the case, set the selection switch to OFF and disconnect all test leads in order to avoid electric shock hazard. Do not switch the device on before the battery/fuse compartment door is closed securely.

If your DVM205AM should not be operating properly, check the battery and fuses to make sure they are not faulty and are properly inserted.

a) Install or Replace a Battery

The battery should be replaced when "BAT" appears on the display. Turn loose the screws at the back and open the case. Remove the old battery (when replacing) and install a new one (1 x 9V-battery type 6F22 or equivalent) - mind the polarity! Close the case and tighten the screws.

b) Replace a Fuse

The fuse rarely needs to be replaced; a blown fuse is usually the result of the operator's error. Turn loose the screws at the back and open the case. Replace the old fuse (250V/0.5A fast blow for 400mA range; 250V/10A fast blow for 10A range), close the case and tighten the screws.
