Calibration Manual

Replacing the Battery

Replace the battery with a 9-V battery (NEDA A1604, 6F22, or 006P).

XWWarning

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. If the display shows “bAtt” the Meter will not function until the battery is replaced.

Replace the battery as follows, refer to Figure 1:

1.Turn the rotary knob to OFF and remove the test leads from the terminals.

2.Remove the battery door by using a standard-blade screwdriver to turn the battery door screws one-quarter turn counterclockwise.

3.Remove the old battery and replace it with a new one.

4.Align the battery leads so that they not pinched between the battery door and the case bottom.

5.Secure the door by turning the screws one-quarter turn clockwise.

Testing Fuses and Current Circuitry

If a test lead is plugged into the mA/∝A or A terminal and the rotary knob is turned to a non-current function, the Meter chirps and flashes “LEAd” if the fuse associated with that current terminal is good. If the Meter does not chirp or flash “LEAd”, the fuse is bad and must be replaced. Refer to Table 17 for the appropriate replacement fuse.

After replacing the fuse, use the following procedure to verify the integrity of the new fuse and the current circuitry. Refer to Figure 3.

1.Turn the rotary knob to N.

2.To test F2, insert a test lead into the Iinput terminal and touch the probe to the A input terminal.

Note

The input receptacles contain split contacts. Be sure to touch the probe to the half of the receptacle nearest the LCD.

3.The display should indicate between 00.0 Ω and 00.5 Ω. If the display reads OL, replace the fuse and test again. If the display reads another value, further servicing is required.

4.To test F1, move the probe from the A input terminal to the mA/UA input terminal.

5.The display should read between 0.995 kΩ and 1.005 kΩ. If the display reads OL, replace the fuse and test again. If the display reads another value, further servicing is required.

XWWarning

To avoid electrical shock or personal injury:

•Remove the test leads and any input signals before replacing the battery or fuses.

•Install ONLY specified replacement fuses with the amperage, voltage, and speed ratings shown in Table 17.
