Page 3: Meter Description
Meter Description Front Panel LCD: 6000 count LCD with Backlight. ▲ button: In SETUP mode, press the ▲ button to increment value by 1. Press and hold the ▲ button for over 2 seconds to increment value swiftly. In Recall mode, press the ▲ button to display the next stored data location. - Page 4 FEET / METERS button: In cable length mode, press the FEET / METERS button to select units of Meter (M) or Feet (FT). LED: If the light is on, measurements are for both inductive and resistive materials. If the light is off, measurements are for resistive materials only. 10.

Page 6: Operation
Operation Note: The battery is charged before shipment, operation when first received is permitted. When in Resistance mode, zero the range before making measurements. After the START/STOP button is pressed to start measurement, the unit cannot be stopped until the first measurement is completed. When the LED light with inductance symbol is on, this indicates the measurement is for both resistive materials and inductive materials. - Page 7 LED ON (6, 60, 600 and 6000Ω ranges) Resistance measurements with the Connect the test leads to the meter. Turn the switch to a proper measurement range. Five dash lines (-----) will be shown in LCD. Zero the range before making measurements. Connect the Kelvin clips together and press the START / STOP button then press the Zero button.
- Page 8 Alarm Function Press the button to enable the alarm function after the HI and LOW limits are set. The symbol will be displayed in the LCD. If the resistance measured falls within the range of HI and LO limits, a symbol of PASS is shown in the LCD.
- Page 9 Recalling pre-stored Ω/LENGTH data There are up to 20 pre-stored Resistance per unit values stored into memory. These values can be recalled and used for cable length measurement. In SETUP mode, press the RECALL button to recall pre-stored data. Press the SELECT button until the resistance per unit values appear. Press the RECALL button to step through the stored values.
- Page 10 Battery Charging The battery should be recharged when the low battery icon appears in the display, after extended use or after a long period of storage. Connect the AC Adaptor to the meter. Turn the rotary switch to an ON position NOTE: The battery will not charge with the rotary switch in the OFF position Battery Replacement The charging circuit is designed only for the lithium battery included with the meter.
