Series

1. If meter under test is not

connected to the instru-

ment output terminals

perform the connection

procedure above.

2. Obtain the desired

base

frequency using the

applicable procedure.

Depress the

DECADE

S*>

keyswitch to place

the instrument in the

Error Mode and

move the

cursor over the MSD

(only digit accessible for

modification) of

the

frequency.

4. With the

EDIT

switch modify the

frequency as

desired.

2-79.

dBm

ERROR MODE

OPERATION

2-80. In the dBm Error Mode the

displayed error is in

rather than a percentage.

Modification

to the base

figure is

in dBm and the error on

the

Central Display is

changed accordingly.

2-81.

Check the dBm

Error Mode operation using

the

following

procedure:

the

meter

under test

not connected

to the

instrument output

terminals perform

the con-

nection procedure above.

2. Obtain the desired base

output

in dBm using the

applicable

procedure.

3. Place

the instrument in the Error Mode

using

the

procedure

described above.

With the EDIT switch modify

the base output

until the meter under test reads

the desired

setting.

The Output Display reads the

dBm required to

obtain

the proper reading and the

Central Dis-

play

shows the difference from

the base in dB.

NEW

EF/CAt.1£1Gpera i i on

2-83.

This switch

performs

two different functions,

dependent upon

the

status

of the instrument. The New

Reference

function is available any time the instrument is

the Error Mode, while the CAL 1

OHM function

requires that 1 ohm resistance be

selected also. The

sequence of

operations for each

is given below.

2-84.

NEW REFERENCE

OPERATION

2-85.

the

keyswitch

depressed when the instru-

ment is in

the

Error Mode

the

output, as modified by the

edit feature

the error mode, becomes the new base

except in the

fractional scale

mode when the full scale

reference is not changed. Error mode modifications and

percent of error figures wilt be on the new base establish-

ed with the NEW REF/ CAL 10 keyswitch.

2-86.

CAL lO

OPERATION

2-87.

This feature is used to compensate for the re-

sidual resistance during two-terminal (internal sensing)

operations. Use the

following

procedure for

the

CAL

sequence:

Connect

the test ohmmeter using the two-

terminal method.

2. Select internal sensing and program a 1 fi

output

from the instrument.

3. Use the error mode

and

modify the instrument

output until

it reads the

same

the meter under

test.

NOTE

The meter under test must be

reasonably

accurate

(+/-%)

and

must

read

between

1.00000 and 1.99999 ohms

for

the

CAL

/£!

feature

to operate.

4. When the instrument

output and the meter

under test read the

same depress the NEW REF

OHM CAL keyswitch,

5. The residual resistance is automatically added

any resistance range selected up to 10 Kiiohms

long as the resistance function is

selected,

remains on internal sense, and the

instrument

not reset, by either removing power or a

CLEAR

ALL command, or until a

new' value

of residual

resistance is

entered.

NOTE

the switch is depressed when the instrument

display

isgreater thanl .99999 ohms, acorrec-

tion

zero ohms is stored. In addition, the

instrument operates as in the NEW REF

mode discribed above.

2-88. Fractional

Scale

Operation

2-89.

Fractional Scale

Operations allow

the operator

to output

and

modify for Error Mode

operations

some

fractional value

the base

output while the displayed

error

is computed

on the original value. (Fractional scale

entries

must

be in units; multiplier,i.e., exponents cannot

be used.) It is intended for use with a meter under test that

has its accuracy at fractional-scale magnitudes

specified

as a percent of full-scale.
