1. V
Ω
Hz% , Voltage, Ohms, Frequency, Duty cycle,
Capacitance, Diode Input Terminal
This is the positive input terminal for Voltage, Ohms, Frequency,
Duty cycle, Capacitance, Diode measurements.Connection is made
to it using the red test lead.
2. COM Common Terminal
This is the negative (ground) input terminal for all measurement modes
except current.Connection is made to it using the black test lead.
3. Temperature Input Jacks:
Remove leads and slide the temp swith to the right to close lead jacks.
4. Display
The display indicates the measured value of a signal, function mode,
and annunciator.
5. / / Button: Shift ranges.
6. ZERO Button
On the DC current ranges, the /ZERO button works as the zero mode,
and on other functions, the
/ZERO button works as the relative mode.
Press REL button again to exit the mode.
Press ZERO button for more than 2 seconds to exit.
In the Relative mode, the value shown on the LCD is always the
difference between the stored reference value and the present
reading. For example, if the reference value is 24.00V and the present
reading is 12.50V, the display will indicate -11.50V. If the new reading
is the same as the reference value, the display will be zero.
7. Function/Range selector rotary switch
This rotary switch selects the fuction, and selects the desired range.
8. INRUSH Button
The INRUSH function captures the starting current precisely in the
beginning of 100-millisecond period when current is just started.
The INRUSH function is used in the AAC range.
