Temperature measurements

Do not touch any live parts with the temperature measuring probe.
 Set the rotary switch to the
is connected, the current environmental temperature is displayed.
 Place the adaptor socket between the "VΩ
with "VΩ ").
 Plug the thermocouple (type K) into the adaptor socket (align "+" with "+").
 Hold the tip of the temperature probe against the object under test.
 Read the temperature on the LCD.

Current Measurements

Do not measure current in circuits with voltages > 1000V
Current measuring jack µA/mA max. 600mA.
For currents up to 10A use the 10A jack.
Always be careful when working with voltages above 60Vdc or 30Vac rms.
Keep your fingers behind the probe barriers at all times during
measurement.
 For measurements up to 600mA: connect the red test lead to the "µAmA" jack
and the black lead to the "COM" jack.
 For measurements up to 10A: connect the red test lead to the "10A" jack and
the black lead to the "COM" jack.
 Set the rotary switch to the µA range for measurements up to 600µA (only when
test probe is connected to the µAmA jack).
 Set the rotary switch to the mA range for measurements up to 600mA (only when
test probe is connected to the µAmA jack).
 Set the rotary switch to the A range for measurements up to 10A (only when test
probe is connected to the 10A jack).
 Press the SELECT button to select DC current (DCA) or AC current (ACA) mode.
 Connect the test probes in series with the circuit.
 Read the measured value from the display.
Notes:
o for DC-current measurements, when a negative polarity is present at the red
test lead, the indicated value is preceded by a "-" sign.
o The µAmA-range is protected against over current with a F630mA 1000V fuse,
the 10A-range is protected against over current with a F10A 1000V fuse.
8. Maintenance
Do not replace internal parts yourself. Replace damaged or lost accessories
by identical ones with the same specifications. Order spare accessories e.g.
test probes at your dealer.
a. General maintenance
Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or
solvents.
b. Fuse Replacement
Switch off the multi-meter, disconnect the test leads from the test points
and remove the test leads from the measuring jacks before replacing the
batteries or fuses.
Refer to the illustration on pages 3 of this manual.
 Remove the 4 screws at the back (indicated with
open the meter.
