Maintenance

XWWarning

To prevent electrical shock or personal

injury, have the Product repaired by ECOM

Instruments GmbH or an ECOM authorized

service center to keep Product certification.

General Maintenance

To clean the external surfaces of the Product, wipe the

case with a damp cloth and mild detergent. Do not use

abrasives or solvents.

Dirt or moisture in the terminals can cause incorrect

measurements and can falsely set off the Input Alert

feature. Clean the terminals as follows:

1. Turn off the Product and remove all test leads.

2. Shake out dirt that can be in the terminals.

3. Soak a clean swab with mild detergent and water.

Move the swab around in each terminal. Dry each

terminal with canned air to push the water and

detergent out of the terminals.

Fluke recommends calibration for the Product in two-year

intervals by Fluke.

Fuse Test

As shown in Figure 10, with the Product in the N

function, put a test lead into the  jack and place the

probe tip on the other end of the test lead against the

metal of the current input jack. If “” appears in the

display, the probe tip has been inserted too far into the

amps input jack. Lift the lead out a bit until the message

no longer shows in the display and OL or a resistance

measurement shows in the display. The resistance value

must be as shown in Figure 10. If the tests give

measurements other than those shown, have the Product

serviced.

XWWarning

To prevent electric shock or personal injury,

remove the test leads and all input signals

before you replace the batteries or fuses. To

prevent damage or injury, install ONLY

specified replacement fuses with the

amperage, voltage, and speed ratings shown

in Table 9.
