13 Holding Measured Values, Performing Single
Measurements, and Zero-Level Compensation
You can specify or execute the following items.
•
Holding measured values (Hold, HOLD)
•
Single measurement (Single Execute, SINGLE)
•
Zero-level compensation (Cal Execute, CAL)
Holding Measured Values (Hold, HOLD)
The hold operation stops data measurement and display operations for each data update interval and holds the
display of all measurement function data. Numeric data list output through the D/A output and the communication
values all reflect the held numeric data.
During integration, the display is held, but measurement continues without stopping.
For information about how holding works during integration, see the sections on holding integration and
releasing the hold.

Single Measurement (Single Execute, SINGLE)
While the display is held, the signal is measured once at the data update interval, and then the display is re-held.
If you press SINGLE when the display is not held, measurement restarts from that point.
Using an External Signal to Hold Measured Values and Perform Single Measurements
(Option)
On models with the 20-channel D/A output option, you can use the remote control feature to hold measured
values and perform single measurements. For details about the remote control feature, see appendix 4.5 in the
Getting Started Guide, IM WT5000-03EN.
Zero-Level Compensation (Cal Execute, CAL)
Zero-level compensation is the process of creating a zero-input condition using the internal circuit of this
Instrument and setting the level at that point to the zero level. It must be performed to meet the specifications of
this instrument.
• Tapping Cal Execute or pressing CAL executes zero-level compensation.
• This Instrument automatically performs zero-level compensation after you change the measurement range or
input filter.
• To make accurate measurements, we recommend that you execute zero-level compensation after warming
up the instrument for at least 30 minutes. Also, the ambient temperature should be stable and within the
specified range (see chapter 6 in the Getting Started Guide, IM WT5000-03EN).
• If the measurement range and input filter remain the same for a long period of time, the zero level may
change due to the changes in the environment surrounding this Instrument. If this happens, we recommend
that you execute zero-level compensation.
• There is a feature that automatically performs zero-level compensation during integration (integration auto
calibration).
