This key sequence clears the entire contents of the Review array. Review data
must be presently shown on the display to clear the array.
LOCAL K When under remote control without lockout (REMS), this returns control to the
front panel.
COMM K L Allows you to set up the computer interface port.
ZERO
K O
While the Totalizer count is displayed, resets the Totalizer to 0.
SINGLE K Q Forces an immediate scan of all defined channels. If a scan is presently in
progress, this new request is ignored. Once begun, the full scan is completed.
Configuration changes are not allowed while a scan is in progress.
Table 1-4. Annunciator Descriptions
Annunciator Description
MON Indicates that the Monitor function is enabled.
SCAN Indicates that the Scan function is enabled. Scanning can be enabled as a single scan
(K Q), with a scan interval, with an alarm-trigger or with an external trigger.
CH Indicates that the channel number is displayed immediately above, in the right display.
SET Lit when the instrument is in Configuration Mode.
Mx+B Lit while Mx+B scaling is being defined and when a measurement on the display has
been scaled with an M value other than 1 and/or a B value other than 0 has been
defined for this channel.
FUNC Lit when a measurement function is being defined for this channel.
ALARM Lit when alarm values are being defined for this channel or when an alarm limit has
been exceeded while measuring.
v Indicates that the measurement function is volts for this channel (used with the AC or

Hz Indicates that the measurement function is frequency for this channel.
°C Indicates that the measurement function is temperature for this channel and that the
degree unit is Celsius.
°F Indicates that the measurement function is temperature for this channel and that the
degree unit is Fahrenheit.
m (milli) a multiplier for the displayed value, e.g., mV for millivolts. Also used when defining
alarm and Mx+B values.
x1 (times 1) a multiplier for the displayed value. Used when defining alarm and Mx+B
values.
k
(kilo) a multiplier for the displayed value, e.g., kHz for kilohertz. Also used when defining
alarm and Mx+B values.
