Dc Current Measurement - Ht 3013 Mode D'emploi

5.7. TEMPERATURE MEASURE WITH TYPE K PROBE
Do not allow the temperature sensor to contact a surface
that is energized above 30 V RMS or 60 V DC, such
voltages pose a shock hazard
1. Rotate the switch on TypeK position
2. Pushing MODE key and select the kind of measure. "°C" or "°F"
symbols are shown at display respectively for Celsius or
Farheneit temperature measurements
3. Insert the type K bead probe in VHz
terminals using the standard adapter and observing the correct
polarity (see Fig. 8). The temperature value is shown at display.
If the probe is unplugged, the instrument makes a sound
4. The "O.L" message on the display indicates the instrument's
over-range condition
5. For HOLD and REL features refer to § 4.2

5.8. DC CURRENT MEASUREMENT

The maximum measurable DC current is 400A. Make
sure that all the test leads are disconnected from the
meter terminals for current measurement
1. Rotate the switch on 40A
value under test is unknown, select the highest range
ey
2. Press REL k to perform the zeroing of residual magnetization
current (see § 4.2)
3. Put the conductor to be tested inside to the center of clamp jaw
to perform accurate measurements (see Fig. 9). The DC current
value is shown at display
4. The visualization of the "-" symbol indicates that the instrument
is connected in a way opposite to the direction of the current on
the conductor
5. The "O.L" message on the display indicates the instrument's
over-range condition
6. For HOLD feature refer to § 4.2
