GETTING STARTED
2.5.1 Model 595 Front Panel
Figure 2-1. Model 595 Front Panel
-
All front panel controls except POWER are momentary contact switches.
Many control buttons include an annunciator light to indicate the selected
function. Some buttons have a secondary function that may be entered
by pressing first SHIFT then the desired button. All such secondary func-
tions are marked in yellow as is the SHIFT button. The controls are color-
coded into functional groups for ease of operation.
cl
1 POWER-AC POWER switch turns unit on or off.
SHIFT-Enables access to secondary features (highlighted in
yellowl.
METER BLOCK
cl
3 CURRENT-Configures the Model 595 to measure current from 1fA
to 2oofi.
El
4 CAPACITANCE-Configures the Model 595 to measure capaci-
tance from .OlpF to 20nF.
w (SHIFT) Q/t-CAPACITANCE display modifier. Displays current,
which is measured at the end of each capacitance measurement.
q
6 SUPPRESS-Makes measurements relative to a stored baseline
reading. Next reading is saved and will be subtracted from all subse-
quent readings. Applies only to current or capacitance
measurements (not Q/t).
0
7 C/Co-Divides all readings by a user-stored Co value. Applies only
to capacitance readings (not
Q/t
or I).
q
8 (SHIFT) STORE Co-Saves next reading as the Co value for C/Co.
0
9 RANGE-Increments or decrements range (sensitivity). Three
capacitance ranges and eight current ranges.
cl
10 ZERO CHECK-Used as a standby condition. No readings can be
taken when enabled.
