600 Ω

Press the SELECT button to select the lowest 600 Ω range for lower resistance measurements. It is

an extended range to complement the AutoTect resistance function.

µA dc and µA ac

Turn the rotary switch to the µA position, µA dc is the default function. There is no annunciator for

dc. Press the SELECT button momentarily to select µA ac. The ac annunciator B appears.

Do not attempt to repair this meter. It contains no user serviceable parts. Repair or servicing should

only be performed by qualified personnel.

Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If

the meter is not to be used for periods of longer than 60 days, remove the battery and store it

separately

If the instrument fails to operate, check battery, leads, and replace battery as necessary. Double-

check operating procedure as described earlier in this manual.

If the display locks up, press the SELECT button for approximately 6 seconds to reset the

microprocessor.

If the instrument voltage-resistance input is subjected to high voltage transient (mostly caused by

lightning or switching surge to your system) by accident or abnormal conditions of operation, the

series fusible resistors will react (become high impedance) like fuses to protect the user and the

instrument. Most measuring functions through this input will then be open circuit. The series fusible

resistors and the spark gaps should then be replaced by qualified technician. Refer to the LIMITED

WARRANTY section for obtaining warranty or repairing service.

If the meter starts up with persistent resetting display or with low battery icon N turns on, replace

the battery. The meter uses one 3 V coin battery IEC-CR2032.
