34. AVG (Average Value in the
Recording mode).
The value displayed is the true average of
all readings taken since the Recording mode
was entered.
35. REL (Relative mode).
The value displayed is the difference
between the present measurement and the
previously stored reading.
36. (Diode test).
The value displayed is the forward voltage
of the ends of the semiconductor.
37. HOLD.
Displayed when the Hold mode is selected.
38. (Compare mode).
Displayed when the Compare mode is
selected. This mode allows you to do the
GO-NO GO test (See "Symbol").

The value displayed is the temperature in
Centigrade scale.
40. °F (Fahrenheit degree).
The value displayed is the temperature in
Fahrenheit scale.
41. The following symbols indicate
the unit of the value displayed.

42. RC-232C TERMINAL.
The standard D9 male connector of the RS-
232C serial cable (UD50RS) is plugged into
this terminal when interfacing to a PC. The
RS-232C serial cable is optional.
Auto-Power-Off Mode
If this Meter is on and inactive for
approximately 30 minutes (1 hour in
the Recording mode), this Meter will
automatically switch to Auto-Power-Off
Mode. To resume operation, turn the rotary
switch back to the OFF position and then
turn the Meter on again.
To disable the Auto-Power-Off Mode, turn
the rotary switch from OFF to any function
(ON) position while holding down the HOLD
button.
Using Test Leads
Use only the same type of test leads as are
supplied with the Meter. These test leads are
rate for 1200 volts.
Although these test lead are rated for 1200
volts, do not try to measure any voltage
greater than 1000 volts DC or 750 volts AC.
NOTE: In some DC and AC voltage ranges
with the test leads not connected to any
circuit, the display may show fluctuating
